Sorry, your BIOS is broken and you're going to have to boot from floppy images.

ISOLinux may consider my BIOS broken, but nothing else does. Plus the boot
floppies don't work any better. (i.e. they fail even worse. with no real error
message, just saying the boot failed & press any key to retry afetr changing the

Is there some reason we can't have isolinux fixed to make allowances. Obviously
the BIOS isn't completely broken or previous versions (i.e. 7.x) wouldn't boot
Comment 3 Jeremy Katz 2003-07-11 14:43:35 EDT
Your floppy failure just sounds like bad floppies.  isolinux uses the hard drive
emulation portion of the El Torito standard so that we can actually fit more
into the boot image without having to require lots of floppies; unfortunately,
there are some BIOSes which just do not properly support this mode, especially
from the timeframe which the PC330 is from.
