I'm trying to flash the BIOS on my GTX 580's to raise their voltage limit. I have created a USB boot disk with nvflash.exe and an edited version of autoexec.bat along with the new BIOS image.

When I boot from the USB stick all appears to be going well and I get into DOS mode. However upon trying to execute the procedure I get a DOS error message saying something like "no DPMI memory available". I know this stands for "DOS protected mode interface", but I can't find a way round it.

Does anyone have any ideas?

Cheers.

Was it something tricky?

Not really, I had to remove the HIMEM.sys file from the boot directory. All went according to plan after that. It was a bit nerve racking flashing £900's worth of GPU though.
