Question about Toshiba Sm-352 Cd-rw/dvd Drive

1 Answer

Do I connect the cable from the motherboard (that has a 4 pin male connector) to the drive, or does ONLY the ribbon cable and the female power connector attach to the drive?

I connected the ribbon and power cables to the drive, but error msg on boot-up says loose or disconnected cable.

D945gtp how to connect cd-rom hardware

1) IDE {PATA} DVD burner drive:

For an IDE { PATA } DVD burner, connect to the 40-pin IDE header on the motherboard. This is located to the right side of the Ram Memory slots.
It is the longer header that has 40 contact pins. {39 actually}

( The shorter connector on the motherboard is for a Floppy Drive.
{34 pins} It is above the IDE 40-pin connector )

The IDE connector on the motherboard should be keyed. Should have a cutout on one side. This is so the Number 1 pin in the flat IDE ribbon cable, will line up with Number 1 pin in the motherboard connector.

Some flat IDE ribbon cables, do not have a Locating Lug on the connector. (Small rectangular 'bump')

Number 1 pin on the IDE ribbon cable will be on the side that has a faint RED stripe on it.

Number 1 pin in the motherboard connector is at the Bottom, with the motherboard installed.

The side of the flat ribbon IDE cable that has the faint red stripe on it, goes DOWN, when installed in the motherboard connector.

If the DVD drive does not have a cutout for it's circuit board, the faint red stripe of the flat ribbon IDE cable, goes towards the power cable connection.

2) SATA DVD burner drive:
You have 4 Serial ATA headers (Connectors) on the motherboard.
Your SATA harddrive should be plugged into the SATA1 header.

You can choose any open available SATA header, to plug your SATA DVD burner drive into.
BIOS will see it once you turn the computer on.

3) If you somehow have been using an IDE {PATA} harddrive, and have it connected to your IDE connector on the motherboard, you SHOULD not use a DVD drive on that flat IDE ribbon cable, also.

BIOS has to find which device has the Operating System on it, (Windows), and then hand the computer over to the Operating System.

To state again, BIOS will look at both devices connected to that flat ribbon cable. The Harddrive, and the DVD drive.
It will then determine that the Harddrive, is the device that has Windows on it, not the DVD drive.

This slows the computer down, and could result in a blue screen.

If you have an IDE harddrive plugged into the motherboard, it would be best to use a SATA DVD drive.

For additional questions please post in a Comment.

The Acer Aspire E500 Desktop PC uses an Acer MBP2207024 motherboard,

I'll be referring back to the photos of the motherboard, at the bottom of the page of the above link.

Start with the power cables coming from the Power Supply, to the motherboard.

1) 24-pin ATX main power cable, and corresponding connector on motherboard:

Middle and bottom photo. Look at the top left side. There is a whitish long connector, with 24 socket holes in it, on the motherboard.

Here is an average example of the power cable, and the connector on the motherboard,

[Note* Color of connectors does Not matter ]

2) 4-pin ATX +12 Volt power cable:

It's hard to see in the photos. Go to the bottom photo.
From the left side; look at the purple Keyboard port, and green Mouse port.
Go to the right to the blue VGA port. (15 socket holes. 3 rows of 5)

Now go to the stack of 3 ports to the right of the blue VGA port.
Two USB, then a Firewire port on top. Right behind this stack, is the square 4-socket hole, whitish 4-pin ATX +12 Volt connector.

Average example of motherboard connector, and corresponding power cable,

Note that on the male power cable connector, for the 24-pin power cable, and the 4-pin power cable, there is a Lock.
Shown more visibly in the middle photo of the above link.

This Lock acts like a see-saw on a playground. The top is squeezed in, and this action releases the hook at the bottom end, away from the tab on the female motherboard connector.

To ensure that these power cables are plugged in tight, the Lock needs to be in the lock position, over the tab on the female motherboard connector.

This power cable is power for the Processor.

That's it for the motherboard.
There should also be a SATA power cable coming from the Power Supply, to the SATA harddrive.

Average example of a SATA power cable,

There are two cables going to a SATA harddrive. The SATA power cable has the longer connector. It has 15 pins. Note that there is also an L shape on the inside of the connector. Lines up with the L shape on the harddrive.

The other cable is a Data cable. (information cable)
It has 7 pins, and is the shorter of the two.
Average example of a SATA data cable, and corresponding connectors on a motherboard,

Look at the photos to the top/right. The top photo shows an average SATA data cable. (Color does Not matter)

The photo also shows a Straight connector. This style of connector is usually used to plug into the motherboard. (Sometimes for SATA optical drives, also)

An Elbow shaped connector is usually used on the Harddrive side.


This is a 4-pin standard Peripheral power cable,

Shown connected to an older IDE (PATA) harddrive. It is also used on optical drives, and to computer case fans sometimes.

IF, your SATA harddrive has a provision on the back for a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY use just the SATA power cable.

Otherwise the SATA harddrive will BURN up.
May not happen immediately, but I assure you it will happen.

In the middle and bottom photos on the Ascendtech link, the SATA headers (Connectors) on the motherboard, are Orange, and at the Top/Right.
There are 4 of them.

The beauty of SATA:
Next to the SATA headers on the motherboard will be silkscreened a figure. SATA0, SATA1, SATA2, and SATA3.

Or it may have SATA1, SATA2, SATA3, and SATA4.

A harddrive should plug into SATA0, or SATA1.
HOWEVER, the beauty of SATA, is that you can plug the harddrive into ANY of the four SATA connectors on the motherboard, and BIOS will find it.

The plastic front of your computer is the Front Panel.

The rectangular block of plastic with pins sticking up out of it, on the motherboard, that the wires from the Front Panel go to, is the Front Panel header.

Sometimes abbreviated as F_PANEL, or FP1, or PANEL_1.

Looking at the Top motherboard photo, it is the blue rectangular connector, at the Bottom corner.
In the Bottom motherboard photo, it is all the way to the Bottom/Right corner.

(Middle photo all the way to the right corner)

The CPU Fan, (Central Processing Unit, or also known as Microprocessor, or Processor for short), cable connects to the small 3-pin whitish connector, that is towards the top of the motherboard, and above the 24-pin ATX main power cable connector.

The System Fan, (SYS_FAN), or computer case fan, connects to the small 3-pin connector to the Right, of the 4-pin ATX +12 Volt connector, on the motherboard.

Front Panel header pinout to follow in a Comment.

I would like to know what adapter (DVI to VGA Cable Adapter) I need to connect to a Macintosh G4. Thanks

Without knowing what Model Number of MAC G4 you're referring to, I can only give you generic information.

If your MAC G4 has a DVI port it is generally the female style.
The DVI connector on the adapter will need to be a male DVI style.

The VGA end of the adapter will be either male, or female. Most VGA connectors on a monitor cable have a male VGA end.

(The DVI end will have the pins sticking out on the adapter. The VGA end will have the socket holes)

Also stated as the monitor cable end will be a DVI male. The port {Connection} on the computer is a VGA female)

Example of a DVI male to VGA female adapter,

Barring that you need the other style of DVI to VGA adapter, (DVI female on the monitor cable, VGA male on the computer), this is an example,

[ Note* The newer VGA connectors are also known as an HD-15 connector.
More information on the Video Graphics Array connector,

More information on the DVI connector styles, and the Digital Visual Interface technology,

If you should find all of this confusing, simply state in a Comment as to what connector is on the end of the monitor cable, and what connector is at the computer.

State whether the connectors are Male (Pins sticking out), or Female (Socket holes)

I was unable to power up my 8250 and I have oirdered a new power supply. Is this difficult to install and is there a set process to follow?

Not difficult at all.

1) Work on a table. Computer unplugged from power, computer case open. TOUCH the metal frame of the computer case. (Not shouting)

[Your body carries Static electricity. Static will fry out the hardware components inside a computer.

Touching the metal frame alleviates the Static. If you get up for any reason in the middle of this, when you come back, TOUCH the metal frame again.

Computer unplugged from power you're safe.
Touch the metal frame BEFORE reaching inside the computer, your computer is safe]

2) To open the computer case:

The above link is to Dell Support>Dimension 8250>Manuals>Service Manual.

This way I can tell you, and show you.
At first glance you'll note this solution is fairly lengthy.
Reasoning is, that I detail out my solutions, so that it is if I am sitting right next to you, and guiding you.

On the main menu, left-click on -
Adding and Replacing Parts

Now left-click on -
Opening the Computer Cover.

All cables removed from your computer, including the power cable.
If you are unsure of where they go, now is the time to make yourself a chart, to refer back to later.

I advise laying a lint-free clean towel on your table, before you lay the computer on it's right side. Keeps the table from being scratched, and your computer case.

As noted the computer is laid down on it's right side.
As you can see there is an elliptical button you press in, on the top, and on the bottom, at the same time.
These are Cover Release buttons.

The left side of the case swings up to the open position.
You should be able to open the left side of the computer case, to a straight up position.

There is one more thing I wish you to do.
Towards the front of the computer, and on the motherboard, is a Front Panel Switch connector.

This connector on the motherboard, is located towards the outside of the motherboard, and right next to the connector for your harddrive's flat ribbon cable. (FRT PNL )

This connector is where all the wires attach from the front cover, (Panel), of your computer. The Power On switch, Harddrive activity lamp, Power On lamp, and so on.

I would like you to take the time now, to draw yourself a chart as to where each wire goes on the motherboard.
Include the color of the insulation of the wires, and if they have any stripes on them.

Make the chart so it shows where they connect on the connector for the motherboard. (FRT PNL)

Yes, I agree, it is a pain.
However, this advice is given in case any of those wires, become unplugged by accident.
There is no ready available information, to tell you how to plug them back in again.
You have this information at your fingertips, right now.

3) Now scroll back up to the top of the page, and this time click on - Power Supply.

Here the information is not very concise.
The statement - 'Then disconnect the DC power cables from the system board and drives'

This means you will be disconnecting all of the power cables leading out of the power supply, that go to all of the hardware components inside the computer.

[System board = Motherboard. Drives = CD/DVD drive/s, and the Harddrive]

I will lead you through each power cable you need to disconnect, and the method of releasing connectors that use a locking device.

A) 20-pin ATX main power cable. Located on the outside edge of the motherboard, to the right of ram memory slot 4.
White in color. 20 socket holes. May have P1 on the connector.

This is a male connector with many wires, that plugs into the female connector on the motherboard.
On the side of the male connector is a locking device.
It's a plastic locking tab that pivots, and has a hook shape on the end.

Squeeze in the top of this locking tab with your fingers, and thumb.
This action pivots the locking tab, and pulls the hook end out of the female connector.

While keeping this lock tab depressed, gently rock the male connector side to side, as you pull up, and out.
Pull only on the male connector, and not the wires.

This link gives you more reference to the 20-pin ATX main power cable connector. Shows photos in great detail,

Note the female connector, shown by itself in the photo all the way to the left, and the lock tab that protrudes from it.
This is what the locking tab on the male connector, catches.

The middle photo shows a little more detail of that locking tab on the male connector, and the male connector itself.

B) Now scroll all the way up this page.
Left-click on the photo that has - 4-pin Peripheral power cable.
(Photo in middle of the top of the page. White connector with four socket holes)

This type of power cable connector will go to your,
Harddrive, and CD/DVD drive/s.

{Click on - Technical Overview in the main menu, to get a better idea of the above statement}

(P3, P5, P6, P8, and P9. Doesn't matter in reality which one you plug in where.
All have a Yellow wire, Red wire, and two Black wires.
When you go to install the new power supply, you can use ANY Peripheral power cable you wish, to any device that uses it. {Your optical drive/s, and your Harddrive)

There is no locking device. The connector is gently wiggled, and pulled straight out.
Sometimes, these connectors are Real Tough to pull out!

(I've had two, in my 20+ years of working on computers, that I could have sworn a Gorilla stuck them in!
Took an Unprofessional method of using pliers on the connector itself, and finesse, to remove them.
Hopefully the same primate didn't install yours)

Note that the Peripheral power cable connector, has two rounded corners.
This is to align it properly, when installing into a device.

Viewing the back of your CD/DVD drive/s, the Peripheral power cable plugs in on the Left side.
(The right side is for a small Audio cable. If you have two optical drives, only one has an Audio cable plugged into it)

Viewing the back of your Harddrive, the Peripheral power cable plugs into the Right side.

C) Scroll all the way to the top of the page. Click on the heading -
Floppy drive power cable
This is a 4-pin Molex connector also, just like the Peripheral power cable connector, but smaller.
(P7 on connector)

It has a flattened out T shape. Only goes in one way into your Floppy Drive.
One, the pins that stick out of the Floppy Drive that this connector goes on, are very TINY.
They are EASILY bent.

Use care, as you go to align the Floppy drive power cable connector, when installing.
Make sure the socket holes line up properly, with the pins on the Floppy Drive.

Two, the pins on the Floppy Drive are SHARP!
You can easily stick yourself!

D) Scroll up to the top of the page one last time.
Click on -
4-pin ATX +12 volt power cable

This is power for your Processor. It MUST be plugged in. Your new power supply will have this power cable.
(This power cable is used for Intel Pentium 4 processors, and above)

This power cable plugs into the motherboard. Has a locking tab on the side of it. Should plug into a small square connector on the motherboard, close to the Processor socket.

(Two Yellow wires, and two Black wires, go into this connector)

Have you purchased a power supply yet, or would you like a recommendation?

One last thing I should bring up.

In the past, Dell had a habit of changing around the wires, in the 20-pin ATX main power cable connector.
(P1 connector)

The color of the insulation on the wires, designates what voltage the wires are using.
(Ground wires are Black, and have no voltage)

1) Yellow is 12 Volts
2) Red is 5 Volts
3) Orange is 3.3 Volts
4) Any Black wire is a Ground wire. (ANY)
5) Green is the Soft Power On wire

Look at the 20-pin ATX main power cable of your new power supply, and compare the color code of the wires, to the Dell's 20-pin main power cable connector.

View the side of the connector that has the locking tab, to orient your view.

Make SURE, the colors of the wires are the SAME, that go into each individual socket hole, on that connector.

If NOT, you will burn up your computer the first time you push the Power On button.

Hmmm.... mainly you have:
-20 or 24-pins connector, that is unique and goes directly to motherboard (powers motherboard and its components)
-4 or 8-pins connector that powers CPU
-the rest would be connectors for ROM (CD/DVD/BlueRay) and HDD devices (there are: molex and sata power conectors)

If you totaly unshure, there is manual:

Orange & white power sw cord needs to be connected to mother board need to know where it goes

Count the number of hole that the SMPS female connector has. It would be in two rows. Look for an opposite male connector with pins in two rows. Number of pins should be the same. There is only one such male connector. Set the female connector on its counter partin such a way that the locking pins of one go into the locking slot of the other.

Unusual Power Requirement

Should not be a problem, the theory here is Volts * Amps =Watts

5V * 2A = 10w

The alternative is to get a LM7505 ($1 or 2) from radioshack or any electronic supply and regulate the 12v down to 5v. its about 1/2 square IC chip.

Pardon my ASCII:
input 1.7V - 35V ________| | |_____ +5v (+/- 1%)
Pin 1 Pin 3

will accomodate 1 Amp (1.25 if heat sinked) for the CMOS version, slightly higher for the olde r(less effecient) version

The other pin is ground. OF course you will want to check the specs and pin assignment for the brand you buy, these are typical.

Toshiba Satellite- A135-S4477 unable to connect firewire

There are generally three different types for firewire connectors. In the laptops its usually the mini contact(type 2) so is even on the camcorders. on the desktop PCs and MACs however it could be. either type 1 or the type 2. There is a thired type (B) which is less common.
The link shows all the types, male and female:

Hope it helped

1 Answer


The main connector to the power supply has to go into the motherboard. Its a rectangle shapped male connector that is on the end of the power supply that plugs into a rectangle female shaped connector on the motherboard. There might also be a shorter square male 4 pin connector at the end of the power supply that should connect into a 4 pin female connector on the motherboard.

After this then you'll want to plug the other connectors into any cd-rom, dvd-rom drives you may have. Same for a floppy drive if you have one. Also make sure your hard drive is hooked up. The connectors that you plug to these devices can only go in one way so no worries about hooking it up improperly. Hope this helps.

After all this, turn on the computer and then after you boot up into windows, make sure you go into my computer and verify that all your drives are being shown in there.
