The problem with booting through the Ultra-SCSI PCI card is that it does not
have a forth code (F-code) PROM on the board. This PROM is required to talk
to the openboot PROM on the motherboard at the ok? prompt. The basic models
of Sun's Ultra-SCSI PCI cards DO NOT have the F-code PROM, Sun Swift does....
X6540A Ultra Wide Dual Single-ended PCI (Symbios glm) NO F-code
X6541A Ultra Wide Dual Differential PCI (Symbios ???) NO F-code
X1032A Sun Swift Fast-Wide SCSI + 10/100 Ethernet F-code
To solve this problem I purchased a Sun EIDE CDROM for the Ultra-5 just to
install Solaris. This has been removed now the OS is on and will be used to
install the next machines.
