I had a spare CMD646 udma-card lying around, and put it in my alpha
(PWS500au). Everything boots fine, but there seems to be no HD

Is the bios (which is x86) strictly necessary to set up the drives? I
tried searching the web for 'udma on alpha' etc. but found nothing.
Thanks,

I am using a Promise 20267 in an DEC Alpha XL 300 with kernel 2.4.10-ac4.
That machine has no bios-support for IDE-Drives, but the kernel (booting
from the ncr scsi-controller) detects my 60gb ibm-disk without problems
and does about 20mb/s.
I've got one real problem:
When I do a "shutdown -r now", the machine is completely dead when loading
the ide-driver after booting up (module).
The only way to get the machine up again is power-cycling.
"shutdown -h now" followed by power-cycle works.
And just now, trying to find out the exact harddisk-model for this mail:
# cat /proc/ide/ide2/hde/identify
-> *boom*, machine dead, network unreachable
Shit - will have to drive to work tomorrow to get my private webserver
back running :(
