Should I expect problems if I add a 20 or 30GB IDE > drive to the system? Well, I did that with no problems - until I turned on USB support. At which time, I ran out of IRQs, so I bought another SCSI drive to replace the IDE drive and get back the IRQ used by the IDE controller. It probably wouldn't hurt to make sure you have an unused IRQ. dmesg is the obvious place to look, but I recall seeing a better method here at one point in the past. > I still want to boot from the scsi.

Is the fact that the scsi controller knows that > the drive is bootable sufficient to get past the motherboard's bios? I think the answer is "it depends" - on your BIOS and it's settings. The only thing that might cause you problems is if your system is set up to check for bootable devices on the IDE controllers first, then checks the SCSI controller. Most likely, it's set to just boot SCSI, or check SCSI before IDE, in which case you're going to be fine. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
