Hi all...
I have a little problem with PIC card/function ordering. Lets see if I can state it clearly...
I have an Adaptec 29320 card, that has two independent channels. Channel B has the external connector and the internal LVD connector. Channel A has one internal Ultra and one other 50-pin scsi-2 connector. I have a ZIP and a CDROM connected to the 50pin plug,
Channel A is limited to 40 Mb/s (do not know if its the card or the fact that I have the 50pin bus used...). So my U320 boot disk has to go to channel B.
Problem is that BIOS detects the drive in channel B as the first SCSI disk, but the kernel (aic79xx driver) detects first the A channel, so my boot disk goes to sdb instead of sda (sda is the zip for the kernel, the CD goes to scd).
In short, I have to install lilo/set root to sdb1. What happens if I remove the zip drive ? Non-booting box :(.
Can I make the kernel to reverse the ordering of the two functions in that PCI slot ? IE, move the U320 channel B to scsi0.
03:02.0 SCSI storage controller: Adaptec ASC-29320 U320 (rev 03) 03:02.1 SCSI storage controller: Adaptec ASC-29320 U320 (rev 03)
TIA
