I have P4 3gig pc with an asus p4r800-v motherboard.
Yesterday I tried to reinstall the drivers that came with the board.
The computer restarted, and on startup it asked me to flash the bios. I hit Y, and the bios apparently got flashed, the pc then went to DOS with some program called freedos and had some internet ads in DOS!! Windows would not restart. Since I had just formatted the harddrive, I formatted it again and tried to reinstall windows. Now every time I try to install windows I get a screen (blue), that tells me that windows has been shut down, and then lists a reason. One reason was IRQ_NOT_LESS_OR_EQUAL, but everytime I try the error message changes, never seen the same twice!!
I brought out an old empty harddrive, tried with the same result.

So, windows is not getting installed, due to reasons that changes everytime I try.

I try to hit alt F2 during startup to try to reflash the bios, but the computer freezes everytime I hit those buttons...

Anyone have any idea???

Warning: ASUS motherboards and FreeDOS!

Hi all, Ian Trider seems to have solved the mystery of "ASUS ships a broken FreeDOS installer with certain motherboards but they do not know that they ship any FreeDOS at all":

If the BIOS detects a checksum error, it switches to CD-ROM boot and asks for the support CD... and there you see a nice screenshot of FreeDOS 2026a Apr 05 2002 (FAT16, Turbo C) booting up .

Note that somebody forgot to update the Copyright string to say 2002. Then FreeCom 0.83 Beta 32 Dec 03 2001 starts up (no config.sys messages) and SHSUCDX 1.4b (John H. McCoy Oct 2000). Finally the CD-ROM detects that the BIOS checksum is wrong and offers you to recover from that.

In the very end you get an A:\> prompt. Probably THERE somebody forgot to delete parts of the installer (which FreeDOS distro version?) which allowed people to do things like "start SETUP" and destroy their Win boot sectors.
