New motherboard... not a lot works yet :-)

I just got a new motherboard (asus dual athlon). It has a couple of issues...

There isn't a BIOS upgrade for this board availale yet so I expect some of it is just BIOS bugs.

Note for anyone purchasing this board in the future: You *must* set 'PnP
aware OS' to 'No' otherwise nothing works at all (all the devices try to claim IRQ0)... that one stumped me for a couple of hours.

1. The APIC doesn't work. It gets as far printing '..TIMER: xxxx' (io_apic.c line 1507 in my tree) then hangs. Using 'noapic' gets around this.

2. 'halt -p' doesn't power off, it only suspends, and the power button doesn't do anything. /proc/acpi/button has two directories called 'power' in it and one called 'sleep'. All 3 directories are empty. I guess this is just a dodgy BIOS but surely ACPI shouldn't create two identical directories???

None of the devices are listed in the PCI database yet... AFAIK this board is AMD 762MP based. Without ripping apart the machine I can't tell you the exact chip numbers, though.

I'm using kernel 2.4.18-pre7 if it helps.

Try Alan's ac tree - Alan himself wrote some drivers for the AMD 760MPX devices. Perhaps he filled in the pci ids, too.

Robert Love

I'll try that, although the AGP is recognised correctly so I wonder if those patches are already in... the 762 probably has different IDs to the 760.
