As far as I know, most/all CDROM drives can be switched from 512 to 2048 bytes by SCSI commands with no problems. The jumper is just there to set the powerup default, as the workstation's firmware is not clever enough to send the switch command before the OS is up. > I ask because the > last time I connected it (and I don't remember what the switch settings > were) I got messages from the kernel telling me that it required Vendor > Specific commands. I don't think these are related to the jumper, as the jumper is useless bejond initial use if I'm corrent with the above.
