Moin,
after setup a cpu/auth server under VMware I want to build a
fileserver on a old pc. The wiki says, that I can use IDE drives
but in /sys/src/fs/pc there is no driver for a IDE drive. Is it
possible to use IDE disk?
Many thanks
Matthias

See /sys/src/fs/pc/devata.c; IDE == ATA == PATA.
It works; I have 4 IDE disks on my file server. You need to declare
the controllers as apparently not described in plan9.ini(8) (to my
surprise):
ata0=type=ata irq=14
ata1=type=ata irq=15
The bad news is, as jmk noted, that the driver uses programmed I/O,
not DMA, so use of the IDE disks chews up the file server's CPU. I
haven't had time to fix it and just making the cache disk into a SCSI
disk would largely solve the problem; doing the same for `other' would
almost entirely solve it.
