I have a problem after rebooting (warm reboot), when I boot linux first after a cold reboot (power on). This problem disappears if I boot DOS first (after power on). The problem is that the Adaptec BIOS does not detect any devices on SCSI Bus.
ciao, Keyvan.

I have seen this problem on certain (non-Intel) motherboards.  I don't think it is a Linux problem in particular, since it is the Adaptec BIOS which doesn't see the drives, at which point the OS hasn't booted yet.  However both machines with this problem were Linux machines.  

When you boot the machine, wait for the Adaptec BIOS message and press Ctrl-A to enter the BIOS configuration.  (This is just after the memory check, but before the screen clears and shows the LILO prompt).  Choose the first option on the screen (Configuration).  Look for the option to 'Enable Plug and Play Scam Support' and enable it.  Save and exit the BIOS configuration and reboot.  

I'm not certain what it means, but it solved our problem right away.  

As always, be certain your SCSI devices are correctly terminated, you have properly shielded cables and they do not exceed 3 meters if you are using Ultra-SCSI.
