DESPERATE!! Editing the File that Windows 2000 Boots Up with?!?!?

Hi there,

I jsut migrated my 2 HD's from one computer to another but the hardware configurations for the two machines are different.  When i swapped drives from both machines the one machine that got my original computer booted up fine (of course Windows 2000 had to reconfigure for new hardware and lost ones but all wasy fine)..However, when i booted up on my new machine (with my original HDs) Windows came up with the following error message (blue background, white text just before the graphical splash screen):

*** STOP : 0x0000007B (0xEB81B84C, 0xC0000044, 0x00000000, 0x00000000)  INACCESSIBLE_BOOT_DEVICE

When i did a "Safe Mode" load up i saw that it stopped on a file entitled "agp440.sys". found in the Winnt\System32\Drivers directory.  I should mention that my original machine was a HP Vectra XL Pentium 3 (with a builtin graphic card that required AGP access but that expansion slot is NOT on that motherboard), and the NEW machine is a HP Vectra Pentium 4 With an available AGP slot which i now have a G-Force 2 card sitting in.  I am guessing that Windows 2000 is hanging because that agp440.sys driver is for the original computer's customized agp for the builton graphics card.  

Can you tell me how i could go about disabling this loading by windows that it does for "agp440.sys" so that it can skip this process and hopefully get me into windows now?  

If this is of any use, i also installed Windows 2000 again into another directory.  When i boot from this new install my system boots fine.  The reason i cant use this is because i want to "KEEP" all of my original programs working under my already configured OS which included passwords.  If i just started from scratch it would take a very long time to get back things.  I can't do a disk image because both machines have different hardware specs.  Can you tell me the file that windows uses on bootup so then maybe if i can't change the contents of this file then i can at least copy it over top of my original Windows 2000 file (that can't boot up) and hopefully it will work now.

Thanks very much.
