This sounds like a kernel problem, not a problem with the boot loader

Comment 2 Need Real Name 2002-12-03 20:24:26 UTC
Tried to fix this problem with the following lines in grub.conf :
"kernel /boot/vmlinuz-2.4.18-18.8.0 disableapic ro root=LABEL=/"
or :
"kernel /boot/vmlinuz-2.4.18-18.8.0 noapic ro root=LABEL=/"
or :
"kernel /boot/vmlinuz-2.4.18-18.8.0 ro root=LABEL=/ disableapic"
or :
"kernel /boot/vmlinuz-2.4.18-18.8.0 ro root=LABEL=/ noapic"
The result is as before, as can be read in /var/log/dmesg :
"floppy0: no floppy controllers found"

The Asus P4T-E floppy is known to be very very weird and isnt supported by Linux.

Comment 4 Need Real Name 2002-12-16 10:42:15 UTC
Somebody advised me to install lilo as alternative bootloader instead as this
would be a grub-problem, a rather bleak option in my view. 

Still : The same motherboard does not have these problems with the floppy device
when dual-booting into Windows 2000 Professional.

I have the identical problem...RH 8.0, P4T-E MB, floppy controller is not
recognised. There are 2 other bugs open for the same issue, 75687 and 78874.
Please note that during installation the floppy WAS detected. I created a boot

Problem known with (almost all) P4-TE Asus motherboards not recognizing floppy
at boot; the bug does not depend on Rh 8.0, and is reproducible with different
linux distributions too. The floppy is OK once recognized.

I think the bug is reported with several different numbers, i lost count.

Proposed workaround: compile floppy as a module. It delays floppy recognition
and then system works reliably. Tested on RH 7.2, I am recompiling 8.0 to test
it again.
