Is the floppy _drive_ disabled (drive type set to 'none'), or the floppy
_controller_ (in an 'on-board devices' menu)? In the latter case
In any case, the BIOS performs initial assignment of IRQs, so this
conflict is probably a BIOS bug. Do any of the following workarounds
work for you?
- Disable/enable the floppy controller in the BIOS (i.e. invert the
current setting)
- Disable assignment of IRQ#6 by the BIOS, if possible (probably an
option in a menu labelled 'Plug and Play' or similar)
- Add kernel parameter 'pci=usepirqmask' (but the bug this works around
seems to be mostly found in laptops)
- Blacklist the floppy driver:
echo 'blacklist floppy' > /etc/modprobe.d/floppy-blacklist.conf

Any smoothly functioning technology is indistinguishable from a rigged demo.
