This one, combined with the info in the attached diff, make this rather
obvious. The PCI registers and interrupts are not set up by the firmware
so the driver cannot access the device. This is therefore blocked by our
oldest open tickets #3 and #4 and also one of those cases where #5 still
would apply. This is a really old machine, so much so that it doesn't even
provide a local APIC, which makes interrupt routing depend on the pci
module. As suggested in #5, you could check if you have a "PnP OS
Installed" or similar setting in the BIOS (if so try turning it off). Also
if there's an option to enable APICs, by all means turn that one on.
Usually warm rebooting from another OS where PCI configuration is
supported leaves the hardware in an initialized state, therefore allowing
our drivers to pick it up from there. Maybe that's the reason why your
fresh install works, presumably done from another OS and then rebooted,
while cold booting directly into Haiku doesn't.
