Boot from external SCSI CDROM drive ?
Is it possible to boot from an external SCSI CD-ROM drive ? Reason I ask is that I want to free up the drive bay now occupied by the ATAPI CD-ROM drive that came with my Dimension XPS-T500.

Hi Rlight,
I pulled this from another support forum:

Subject: can't open boot device

Ran into this myself.
Did the following and got it working:
1. probe-scsi-all
Locate your cdroms scsi "Target" for instance, 5
2. running "boot cdrom" might show something like this
/sbus@1f,0/espdma@e,8400000/esp@e,8800000/sd@6,0
The one thing that is important is the "sd@6".
**note:::**The "Target" number of your cdrom and the sd@ should match.
For instance, my scsi device was set to target 5, so I booted from sd 5 instead of 6, like:
boot /sbus@1f,0/espdma@e,8400000/esp@e,8800000/sd@5,0
The /sbus or /pci "path" will likely be different from the one listed above. Make sure you specify the correct path or you will continue to receive errors.
If all goes well, then you can modify your eeprom settings with the nvalias command. Modifying the eeprom settings with devalias is temporary and will only last until the next reset.

Many thanks for your reply. However, I posed the question poorly. What I really wanted to know is ... suppose I get rid of my ATAPI CD-ROM (to free up the drive bay it occupies) and add a SCSI CD-ROM drive. Can I add new software by placing the CD for that software into the SCSI CD ROM ?

Hi Rlight,
Yes the SCSI CD-ROM will work just fine for software, games, etc..
The only issue you may see, per say if you installed a game or program that runs off the CD, the program tends to "look" for the drive where you first installed the program. On occasion you may have to uninstall the program and re-install it from the SCSI CD-ROM.
Best Regards
