Hello
I have FreeBSD installed on a ASUS-SP3G mainboard system. I have
been using this system for about a year now with out any problems. I'm
going to slowly upgrade. I purchased a TYAN SCSI controller, which uses
the NCR 53c825 chip. The controller has a internal/external SCSI-II FAST
bus and a internal SCSI-II FAST/WIDE bus. I should have my Micropolis
3243W drive in two weeks. I wanted to test the controller with my current
drives. I disabled the onboard controller and installed the 53c825.
This is my old dmesg:

This repeats four times with simular numbers. It then says it can't
mount root and reboots. Are not the 810 and 825 compatable with each other.
Does anybody have any ideas on this?
BTW: I want to say thank you to everybody who worked on FreeBSD 2.1 is
great.
Thanks, ejc
