I have an IBM 8310 KCU with no harddrive It has been removed from a network and the BIOS will not let me save changes


BIOS = Basic Input/Output System.

A small program that is on the BIOS chipset.

[Chip and Chipset are slang terms for I.C.
Integrated Circuit, ]

In the BIOS program is the BIOS Setup utility.
Also known as just BIOS Setup, or older versions are known as CMOS Setup.

In the BIOS Setup utility is Boot Order.
Tells BIOS what device to boot the computer from.

May be the Harddrive, optical drive (CDROM), removable device, or network device.

You want CDROM as the first boot device.

There will be a list, and CDROM will be in the list. You want it at the Top.
This way when you turn the computer on, it will boot from the Windows operating disk, you have in the optical drive. (CD/DVD drive)

Let's go to Lenovo Support, and take a look at the HMM for your
IBM NetVista A30P - 8310 Desktop PC,

Second list of files -
Netvista A30P (type 8309, 8310, 8311, 8312)
Go to the right, and click on the blue -> MIGR -42835 (10 Aug 2004)

You can either click on all that blue lettering/numbering, or go to the right; and click on the black Down Arrow.
(Under the heading Download)

[Ignore if you are aware;
This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.

(Upgrading to the latest version of Adobe Reader, that the computer you are using now; would be advantageous. Unless it already has Adobe X (10) on it)

After you click on the black Down Arrow, it may take up to 30 seconds before the first page comes up.
The PDF file will not show until fully downloaded ]

When I refer to a page, it will be for the Adobe Reader page number box, at top; and not the actual manual's page.

Go to Page 30.
IBM just names the BIOS Setup utility, as - Setup Utility

AS SOON AS you press the Power On button, start tapping on the F1 key.
Tap in 2 second intervals.
If you hear beeps ignore them. They are Stuck Key Error Code beeps, and it is you that is doing it.

(My method above.
The enter BIOS Setup screen goes by F-A-S-T.
If you do not press the enter BIOS Setup key quick enough, and at the correct time; the opportunity of entering BIOS Setup is gone.
You have to start all over.
This way you will get in )

And that's where the manual leaves us........


I have learned it's a version of a Phoenix BIOS.
Uses this format in BIOS Setup if I am correct,

Scroll down to the last example on the page.
Details the Boot menu.

When you enter the BIOS Setup utility, you can no longer use your mouse. You have to use your Keyboard.
If you look at the bottom of each menu, you will see the Navigation Guide.
Does NOT state navigation guide, however.

Use the Right Arrow key, and highlight Boot.
Now press the Enter key.

Here you can see First Boot Device, Second Boot Device, and so on.
You will also see the various devices that can be booted from, on the right of these subheadings.

You want ATAPI CDROM as the First Boot Device.
(Will explain ATAPI at the end)

Use the Down Arrow key, and highlight First Boot Device.
Press the Enter key.
If I am correct, the cursor should move over automatically, to the list of boot devices on the right.

If I am Not correct, use the Right Arrow key to move over to the list.

Use the Down Arrow key, and highlight ATAPI CDROM.
See if you can use the Minus ( - ) key, to move CDROM to the top.
Tap the key until it does.

(The +/- key is the Change Value key)

Once at the top, press the Enter key.
Now press the F10 key.

Okay, things may differ here also.
It should come up with Save Changes?
It may have a Yes/No, or a Y/N.

You want to use the appropriate arrow key, and highlight Yes, or Y.

It may be also that you press the Y key, or the N key.
These are lower case letters that you press. Do NOT press the Shift key, and the lower case y.
The y is shown as an upper case Y, just for clarity.

The computer will now restart.
Optimally you want the Windows installation disk, in the optical drive; now.

However if it isn't in there, don't sweat it.
Just put it in the optical drive, and close the tray.
Now press the CTRL key, ALT key, and Delete key; AT THE SAME TIME.

This will restart the computer, and the computer will boot from the disk in the optical drive.

Awaiting questions, post back in a Comment.

[When the Power Supply (Computer), is plugged into power, there is a constant 5 Volts present.
The 5 Volt Standby Power.

You press the Power On button, and it in turn presses against the Power On switch.
(The Power On switch is located inside the plastic assembly, of the Power On button)

The Power On switch is a Momentary Contact Switch. Only remains closed for a second, or two.

Closing (Pressing Power On button), the Power On switch temporarily closes a circuit.
The Soft Power On circuit. It uses that 5 Volt Standby Power.

The Soft Power On circuit 'excites' the Power Supply, and turns it on. (Sounds like a seedy novel, lol!)

The first chipset on the motherboard to receive power, is the BIOS chipset.
The Basic Input/Output System program is initialized.

BIOS looks to see what devices are connected, does a Ram Memory count, turns the Processor on; and hands the computer over to the Operating System.

O/S being some version of Windows ]

My laptop is not allowing me to install OS (windows) i suggest mayb its bios securities now how can i remove the security

A) DO NOT post your email address. It's in the FixYa T.O.S.
(Terms of Service)

(Plus it's a worldwide forum. You are opening your email to all sorts of spam)

B) Are you trying to install the SAME operating system?
Example: Windows XP over Windows XP?

Windows does not like to be written over. A type of security.
It definitely does not like the SAME O/S being written over it.

(Same version and build)

Go to BIOS Setup, and to Boot Options.
In Boot Options make sure CDROM is set as the first boot device.

CDROM will be at the top of the list.

SAVE changes.

Your computer will now boot off of whatever is in the optical drive.

Need laptop manufacturer name, and Model Number, to try to guide you in entering BIOS Setup.

{ OR, soon as you turn the laptop on look at the bottom of the monitor screen. Look for;

A) enter Setup, or
B) enter BIOS Setup, or
C) enter CMOS Setup

There will be a key on the Keyboard to press, that is stated next to the above. (Example: enter BIOS Setup/ Delete, or enter CMOS Setup/F2)

Once you see the key, (Screen goes by very f-a-s-t), restart the computer.
(Press the CTRL key, ALT key, and DELete key, AT THE SAME TIME, to restart the computer)

As SOON as the computer restarts, start tapping on the key.
(Tap in 2 second intervals. If you hear a beeping, ignore it.
It is a Stuck Key Error Code )

How do i restore a medion laptop back to factory settings as we have the discs but we have a detachable cd/dvd disc drive. so really struggling to reset things

I will have to assume "detachable" means USB. You will need to enter the motherboard's BIOS setup program --- this is typically accomplished by pushing a key or keys as soon as possible after pushing the power button. Key DEL, F2 or F10 are most likely, but usually the system *tells* you ... look for something like "Press F2 to run setup".

Once you enter the BIOS setup program, look for "Advanced BIOS Features", which is usually the 2nd option in the left column (navigate using your arrow keys and press ENTER/RETURN to select). Using the arrow keys, move to "1st boot device" and select "USB" or "Removable Device". If you don't see either under "1st Boot Option", then *disable* all boot devices (1st boot device, 2nd boot device, etc.) but *enable* "Boot Other Device". This should force your motherboard to boot from the USB CDROM.

If your CDROM is *not* USB, then I'm afraid I've paddled up the wrong creek :-(

Hope this helps!

How are you attempting to enter the setup (BIOS)? Here are the steps:
Press the blue Access IBM button when the message "To interrupt normal startup, press the blue Access IBM button" is displayed to enter the ThinkVantage Productivity Center, then select Start setup utility to open the BIOS Setup Utility.
