I have tried without avail to boot up FreeBSD v. 2.1 and I have tried several of the snaps for 2.2. I keep getting the following message: ah0: WARNING no command for SCB 0 (cmdcmplt) QOUTCNT == 20 Where QOUTCNT decreases to 0 and the machine then reboots. I have tried new SCSI cables, having only one hard drive (Micropolis or Fujutsu) on the controller, running the PCI bus at 60 and 66 MHz, slowing the CPU down and even trying to go through the source code and figure out what is going on. In doing that I enabled the debugging and I noticed something that I thought peculiar... The computer seems to have problems after probing SCSI ID 7. ID 7 is the hard drive controller, so why does it probe the controller? Any help / suggestions / questions would be *extremely* appreciated. -Eric ohms@vt.edu System Setup: Pentiume 133 w/ 16 MB RAM PCI Viper Video Card (2 MB) Sound Blaster 16 w/ Adaptec SCSI controller 2 1-Gig SCSI Hard drives 1 SCSI CD-ROM 1 HP 9mm DAT Drive * Note: I have tried running the system with nothing more than the video card and 1 hard drive, but it still doesn't work.
