Hello,

there is a big problem (at least for me) with SCSI HDDs.

There is a PC with Adaptec AIC-7850 on motherboard and FreeBSD 2.1.0. 
There are three HDDs attached to the SCSI-2 bus:
 ID
----------------------------
 0        Conner CFP1080S        (SCSI terminated)
 1        Quantum Lightning 540S (SCSI not terminated)
 2        Conner CFP2105S        (SCSI not terminated)
 7        AIC-7850               (SCSI terminated)

When FreeBSD 2.1 is booted (I booted by means of install.bat/inst_ide.bat
 under DOS), it detects ahc0, waits "SCSI deviced to settle", then shows 
list of disks' data, and then about 10-15 copies of the string
        "ahc0 WARNING no command for scb 0"
and goes to reboot.

When the HDD with ID 2 is detached from the bus (by removing cabling), 
FreeBSD boots ok. Besides this I tried to insert/remove terminators 
on the HDD, but the problem persists.

The HDD with ID 2 was installed yesterday and there ar 3 partitions
on it, first one is used by OS/2, on second one NT is installed. The
HDD workes fine under those OS. So the hardware configuration seems
to be proper.

Could you please provide any possible solutions for the problem ?

Thanks in advance. Dima.
