Flash BIOS FROM DOS PROMPT

[daveackerman30]

I'm having an issue where when windows XP (media center edition) boot I can't use the mouse or keyboard. I was told I should upgrade or flash my BIOS so I downloaded a the newest BIOS (in EXE) format from Dell's website and saved on a memory card. Since I have no mouse or keyboard when windows loads I'll have to run it from the DOS. I booted up using the Windows XP CD in recovery mode so I can get to a command prompt. From the command prompt I can see the contents of the memory card (call it the H drive) including the .exe file I need to run but when I try to run it from c:\windows>H:\xxxx.exe I get a message stating the command is invalid.

Does anyone know how I can get this .exe to run from the command prompt? Do you need to create a new boot CD (I don't have a floppy) and add the BIOS .exe file? If so what's the easiest way to do that.

Any help would be great.

Thanks

Unfortunately what you are trying to do is run a Win32.exe file in DOS. can't be done, that setup program would have to be written for DOS. Mode Execution.

Flashing Bios is a bit extreme for the repair of a Keyboard and Mousey. I am guessing they are USB and what you really lost was USB support and I am also going to infer you have lost them from the MB side of things. If you have access to another mouse and keyboard hopefully non USB I would try that first, looking to reset the Use legacy USB in your BIOS. (for older systems) for newer I would unplug any extra pci devices as you could also have a IRQ conflict. with out more info on your system that is all I can offer.

I thought the same about the BIOS executable but on Dell's website it says the file can also be run in DOS by booting up from a boot disk. I don't have a PS2 adapter on the PC so I can't try another keyboard or mouse.

The root of the problem started because the PC wouldn't boot and in safe mode I saw it was stuck on Mup.sys. After a little research I found it was a common issue so I can a chkdsk using the recovery console which didn't help. I think restored the registry hive which loaded windows but then I didn't have a keyboard or mouse. Looking at other posts about the Mup.sys error I found that flashing the BIOS could help.

Let me know if you have any other ideas.

Thanks
