Can't find any low performance SCSI disks at all, and 22 MB costs a fortune... :( Even for smaller disk, with same rpm SCSI is almost twice the price... I guess you get what you pay for; SCSI is better; but this time I just wan't it cheap... ;-) > > If you really want to do IDE, you can, but you might have fun with the > system trying to boot from it - which would be a pain in the ass. Yeah, I thought about that... Is there no way to get around that. BIOS? I have an alternative; put the disk on a IDE only workstation, as an IDE slave... But it would be better to have it on the SCSI machine if it will not impact performance. /Palle To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
