Check your disk management, it may not have had a drive letter assigned.

right click my computer, go to manage, choose disk management

right click on the drive there and choose assign a drive letter. Change the letter to an unused drive letter and it will show up.

Tip

Calculating Offsets


This tutorial is more of a tip than a tutorial. It just explains how to calculate offsets for jumps and calls within the program you are patching.

Types of Jumps/Calls

Here I will just describe the different types of jumps and calls which you will come across:

Short Jumps
Short jumps be they conditional or unconditional jumps are 2 bytes long (or 1 nibble if your Californian ;-).These are relative jumps taken from the first byte after the two bytes of the jump. Using short jumps you can jump a maximum of 127 bytes forward and 128 bytes backwards.

Long Jumps
Long jumps if they are relative are 6 bytes long for conditional jumps and are 5 bytes long for unconditional jumps. For conditional jumps 2 bytes are used to identify that it is a long jump and what type of jump (je, jg, jns etc) it is. The other 4 bytes are used to show how far away the target location is relative to the first byte after the jump. In an unconditional jump only one byte is used to identify it as a long unconditional jump and the other 4 are used to show it's target relative position, as with the conditional jumps.

Calls
There are two different types of calls which we will use. The normal type of call works the same as the long jumps in that it is relative to it's current position. The other type gives a reference to a memory location, regiter or stack position which holds the memory location it will call. The position held by the later is direct e.g. the memory location referenced may contain 401036h which would be the exact position that you would call, not relative to the position of the call. The size of these types of calls depends on any calculations involved in the call i.e. you could do: ' Call dword ptr [eax * edx + 2]'. Long jumps can also be made using this method, but I didn't say that earlier as to avoid repetition.

Tables
Here is a brief list of all the diferrent types of jumps/calls and their appropriate op-codes. Where different jumps have the same op-codes 1 have grouped them:

Jump description Short op-Code long Op-Code
call procedure call E8xxxxxxxx N/A
jmp u nconditional jump EBxx E9xxxxxxxx
jae/jnbe jump if above 77xx 0F87xxxxxxxxx
jae/jnb/jnc jump if above or equal 73xx 0F83xxxxxxxx
jb/jc/jnae jump if below 72xx 0F82xxxxxxxx
jbe/jna jump if below or equal 76xx 0F86xxxxxxxx
jcxz/jeckz jump if cx/ecx equal zero E3xx N/A
je/jz jump if equal/zero 74xx 0F84xxxxxxxx
jne/jnz jump if not equal/zero 75xx 0F85xxxxxxxx
jg/jnle jump if greater 7Fxx 0F8Fxxxxxxxx
jge/jnl jump if greater or equal 7Dxx 0F8Dxxxxxxxx
jl/jnge jump if less 7Cxx 0F8Cxxxxxxxx
jle/jng jump if less or equal 7Exx 0F8Exxxxxxxx
jno jump if not over flow 71xx 0F81xxxxxxxx
jnp/jpo jump if no parity/parity odd 7Bxx 0F8Bxxxxxxxx
jns jump if nor signed 79xx 0F89xxxxxxxx
jo jump if overflow 70xx 0F80xxxxxxxx
jp/jpe jump if parity/parity even 7Axx 0F8Axxxxxxxx
js jump if sign 78xx 0F88xxxxxxxx



Calculating offsets (finding in the xx's in table)

You will need to be able to calculate offsets when you add jumps and make calls within and to the code you have added. If you choose to do this by hand instead of using a tool then here are the basics:

For jumps and calls further on in memory from your current position you take the address where you want to jump/call and subtract from it memory location of the next instruction after your call/jump i.e.:

(target mem address) - (mem location of next instruction after call/jump)

Example
If we wanted to jump to 4020d0 and the next instruction *after* the jump is at location 401093 then we would use the following calculation:

4020d0 - 401093 = 103d

We then write the jump instruction in hex as e93d100000 where e9 is the hex op-code for a long relative jump and 3d100000 is the result of our calculation expanded to dword size and reversed.

For jumps and calls to locations *before* the current location in memory you take the address you wan to call/jump to and subtract it from the memory location of the next instruction afetr your call/jump, then subtract 1 and finally perform a logical NOT on the result i. e.

NOT(mem address of next instruction - target mem address - 1)

Example
If we wanted to call location 401184 and the address of the next instruction after the call is 402190 then we do the following calculation:

NOT(402190 - 401184 = 1 ) = ffffeff4

We can then write our call instruction in hex as e8f4efffff where e8 is the hex op-code for relative call and f4efffff is the result of the calculation in reverse order.

If you want to practice with different examples then the best way to do this is to use a disassembler like WDASM which shows you the op-codes and try and work out the results yourself. Also as an end note you don't have to perform these calculations if yo have enough room to make you jump or call instruction into an absolute jump call by doing the following as represented in assembler:

mov eax, 4020d0
call eax (or jmp eax)

Final Notes

Make life easier and use a program to do this ;-)

Good Luck!

The motehrboard bios doesnt boot from usb to install windows, how can i update the bios to boot from the usb?


Insert your USB jump drive into a USB port on the computer containing the bootable program. Copy the information to your jump drive, then insert the drive into a USB port on the computer you wish to boot the program from.

Power on the computer. When the computer begins displaying its startup information, hit the key indicated on screen to enter the computer's BIOS (the "F1" or "Delete" keys are commonly used to access the BIOS).

Browse through the menu options in the BIOS to locate the computer's startup and booting options to locate the "CMOS" menu, which is where you'll have the option to set which devices will boot at startup.

Browse though the list of bootable option---they'll be ordered as "First Boot Device," "Second Boot Device" and so on. Set the USB jump drive as the first bootable option---your BIOS may refer to the drive as a "USB Removable Floppy Disk."

Save and exit the BIOS. When your computer restarts, your program will boot first before your operating system.

How to unlock my bios password?


Removing the CMOS battery like the one shown in the picture to the right will cause the system to loose all CMOS settings including the password. To do this locate and remove the CMOS battery on themotherboard for at least five-minutes. After this has been done put the battery back into the computer and turn it back on.
Jump the CMOS solder beads
Older computers and especially older laptops don't have jumpers or dipswitches and require the user to jump a pair of solder beads on a circuit board. The identification and location of these solder beads can vary and if not available in computer documentation is only obtainable through the computer manufacturer.
If you've identified the solder beads they can be jumped by placing a flat-head screwdriver over the two beads and leaving it on those beads while turning on the computer. Once the computer has booted turn off the computer and then remove the screwdriver.

How to upload pictures by my usb


That really is a matter of if when plugged in to the USB port of the computer you are using, if computer you are using can recognize the drive.

If you are using Windows XP, check "My Computer" and you should see the Kingston USB jump drive showing as an device icon.

In Vista and Windows 7 select "Computer" and you should also see the USB jump drive listed as a device icon.

If you are using a Mac OS X computer with your Kingston jump drive, providing the drive has been formatted with the Mac OS Extended (Journaled) format, or the MS-DOS format (which is readable on both Mac and PC platforms), it will show up
in the Finder sidebar and on your Desktop.

Either platform however, to load pictures onto your Kingston is easy, all you have to do is either copy the pictures from there respective folder or location and either right click on the Kingston 2GB HD icon and paste the pictures.

Or you can double click on the Kingston 2GB USB icon and paste or drag the pictures into the open window of the Kingston 2GB USB jump drive.

That is honestly as simple as it is.

Now, on the other hand, here are a few steps, if you want to upload to an online resource which allows photo uploads from another source, namely your computer..

When you use the upload feature of that website or webpage to upload your pictures to, no matter whether you are on a Mac or PC, you simply have to click that uploader's Browse or Upload button.

Next, simply locate the Kingston 2GB USB jump drive in My Computer, (Windows XP), Computer (Vista , Win 7) or Devices and/or Desktop (Mac OS X).

Then start selecting and uploading your pictures onto that website or webpage with your Kingston as the source drive.

Yes, I have given you a number of options, but hopefully you will see the ease of using any of these methods, again depending on what computer operating system you are using, how easy it is to upload photos from your Kingston (DTIU3/2GB) 2 GB USB Hard Drive.

Regards,

-Mactechtrainer

Need to download a Microsoft Word article from XP system to a memory stick


Usually you just put the memory stick in the back of the computer in a usb drive, wait for it to load up , then you have multiple  options.
First you can go into word and save it directly to the jump drive... this is doe by selection "my Computer on the sleft side of the save prmpt then finding the jump drive.
Second you can save the file to a known location like the desktop then right click the file and click "send to" and findyour jumpdrive it should be at the bottom.
Or if it is already saved to a specific location, like "My Documents" just right click your start button, clcik "explore" then on the left pannel got to the location it is in and click it, then on the right pannel find your file and copy it "right click then copy", then on the left pannel find your jumpdrive and click it then on the right panel right click and hit paste.
hope this helps.
