Two questions for you experts. I really appreciate the help I got on
getting my RAID devices working.
Situation: My motherboad is a BE6 from Soft Switch. It features 4 IDE
connectors. IDE 1 & 2 were detected at install time and are running
with a CDrom drive and 3 HDs. IDE 3 & 4 use the Ultra ATA/66 IDE chip
set. I have been unable to get IDE3 or 4 to work.
Question 1: The drives on IDE 1 & 2 are presently configured (as reported
by hdparm) to not be using DMA mode. Needless to say the cpu utilization
can get quite high when doing copies from disk to disk, and generally
performance is barely adequate. The drives themselves are ATA/66
capable. Can I enable the DMA mode on these disks while they are connected
to IDE1 & 2?
Question 2: Can I get the drives to work at all on IDE3 & 4? I mean that
even if they work at ATA/33 speeds that would still be a huge improvement
over what is happening now? I notice that Kernal 2.3 has added support
for IDE HPT343. I am not sure what the relationship is between this and
what I have, but it sounds like my chip set may not be supported. But
perhaps it is supported, but only in some degraded mode?
Thanks in advance for any suggestions or ideas or pointers,
Robert
