4.1 Basic Problems

If the system cannot work with the adapter, check the following:

Is CMOS setup required to enable PCI bus parameters

Is the adapter installed in a bus-master PCI slot

Are all the cables connected correctly

Does the configuration follow the SSA rules for this adapter

If the system cannot access the SSA disk drives, check the following:

Is power turned on to the disk drives

Has the configuration utility been run for all the required disk drives, and do they appear in the list of attached resources

Are the disk drives connected in a loop, either from SSA loop A port 1 to SSA loop A port 2, or from SSA loop B port 1 to SSA

loop B port 2?

Is the light next to the adapter-loop ports on, showing that both ports are operational

If the system fails to boot from an SSA disk drive, check the following:

That there is not an IDE disk drive installed

That there is not a SCSI adapter with BIOS enabled installed in a higher-priority PCI slot than the SSA adapter

That the CBIOS enable

That the SSA device drivers are loaded before the SCSI device driver

That the address (drive letter) of the partition from which you are trying to boot has not changed. (Adding extra drives can cause

the addresses of existing drives to be changed.)
