Hi,

Need help with the following, please:

This is my configuration:

Terminated, 2G Western Digital Wide SCSI hard drive ( 16 bit), 
Terminated 12/20 Plexter CDROM ( 8 bit ) SCSI.
AHA-2940UW SCSI host adapter
Micron Millenia board.
Besided the controller card there is just the video 
card.

Sync and Disconnect are both disabled for all the 
devices in the SCSI chain ( hard drive, CDROM, 
and controller ). 
Mother Board BIOS: Phoenix v4.04
Host adapter BIOS: v1.32
PNP is disabled.

Partitions:
Primary active DOS partition: 250M win95
Rest: Unused.

I have a problem when booting FreeBSD with the 
install floppy: /RELEASE2.2.6/updates/boot.flp,
see below for boot dmesg output
By the way WIN95 runs fine, and had FreeBSD runing
when I used a buslogic controler on a regular SCSI
drive (  2G )

Have tried the following:
- Disconnecting the CDROM.
- Taking out the controller and booting untill 
  "No Operating System", then rebooting again.
- Moving the controller to different PCI slots.
- Sync, and disconnect enabled.
- Searching around for this problem on the net.

Below:
