If your system contains more than one type of host adapter, SCO OpenServer might find the secondary adapter first and assume it is the controller for the root disk. In this case, Upgrade might not be offered as an option for Installation type. If this happens, restart the installation and specify the location of your root hard disk at the boot prompt.
For example, if the root disk is at
ID 0 on the first bus of an Adaptec 294x host adapter,
enter the following at the boot prompt:
defbootstr Sdsk=alad(0,0,0,0)
If the root disk is on a second adapter of the same type, enter the
following:
defbootstr Sdsk=alad(1,0,0,0)
If you have a different SCSI host adapter, use the appropriate driver name instead of alad. The following table lists the supported SCSI host adapters and the corresponding driver names.
