According to the manual, it only allows you to do it in DOS... So with no floppy drive, you can do it from the hard drive as long as you put the update .exe file on the C drive where you know here it is along with the BIOS file, this is an example:
C:/updatefile.exe
C:/BIOS.rom

You can then run the ezeupdate and navigate to the BIOS file, or press F8 before the windows splash screen and boot to a DOS prompt and run the update.exe file...

Worth noting though on an elderly motherboard, proceed with caution as it is easier to hose it with a bad flash than a newer one these days...

You could also make a bootable USB stick for DOS as well. Or boot from the Windows CD and use the files from a USB stick.

Only flash your bios if you have something to gain, not just because there is an update.

Scratch what I said, unless the drive is in FAT format and NOT NTFS....

You can do it within windows though using ASUSLiveupdate, I have used that many times with no issues...

P4P800 Deluxe and P4P800 BIOS V1018Please click on more to read the descriptions before updating BIOS
Do not use old version Afudos.exe to flash BIOS. Must use new Afudos.exe which is included in zip file to flash BIOS.
Using ASUSLiveUpdate to flash BIOS,you need to upgrade ASUSLiveupdate to v 5.22.02 or later before flash BIOS.
Please do not use Ezflash for updating this BIOS unless the pre-loaded BIOS is of version 1014 or 1015.

Not really. Check the release notes. There might not be a good reason. Especially if the board works otherwise.

When in BIOS actions of a motherboard, only FAT-12 is a recognized format. A floppy disk is best, but if not available, then as Mr T noted.. from a DOS prompt. But NTFS is not recognized in basic mode (BIOS=Basic Input Output System). FAT-16 would be acceptable, if a small-size drive were used (200 megs or less). http://support.microsoft.com/kb/118335
The MBR (master boot record) of a hard drive has media descriptors and a 'boot path' to specific files that allow the BIOS mode to transfer to a different file system (bootstrap) handover. If the BIOS has a "legacy USB" mode, then a boot path could be enacted via that method. Restrict the boot path to one device.

That is not a good omen! Windows XP has more than 10 years (08/2001) of service, and should have no qualms about a BIOS inception date back to 2003!! With SP 4, XP still is viable until 2014.
If you get a popup like that, it may be a scam.. or a viral "hit". Best to go to www.windowsupdate.microsoft.com/ for true information.
True, there may be some compatibility problems with ACPI status.. which may require a newer BIOS version. But not always the case.
