SUMMARY Ultra-5, boot path for external CD through SUN Ultra-SCSI PCI

Date: Mon Mar 09 1998 - 07:23:18 CST

Hi Gurus,

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.

> The nearest I got was (i think!!)
> boot /pci@1f,0/pci@1/scsi@1/cdrom@6,0:f
> I have tried sd@6,0 instead of cdrom and scsi@1,1 etc etc

> sd6 at pci1000,f0: target 6 lun 0
> sd6 is /pci@1f,0/pci@1/scsi@1/sd@6,0
> The internal connectors are too close to the case to leave the 68 pin
