The only thing I can change in kernel is enable ultra wide (which for some
reason shows only 20MB/s). This is what I added to my kernel config file:
aic0 at pci? flags 0x00001000
aic1 at pci? flags 0x00001000
aic2 at pci? flags 0x00001000
When the system boots this is what I get:
May 26 22:40:00 volcano kernel: tg0 at aic0 target 2: with disconnect, no
tag queueing, wide, synchronous @ 20.0MB/s
May 26 22:40:00 volcano kernel: sd0 at tg0 unit 0: disk: SEAGATE ST423451W
rev 0013 (SCSI-2) 45322644*512
I think I know how to enable tag queueing... What does it do anyways?
Is there other way of configuring 2940 other than through kernel?
