The max spinup time allowed by the HA (Symbios) is 10 sec. I set
it to that. The max I/O timeout is setable and although I don't
think this is applicable, I set it to 60 sec.

On booting the HA bios immediately finds the correct device (ID=4)
and the cd reads for the full 10 second spinup, then the device
scan
continues to the whole bus, finding all the devices on the chain
and then goes to bootmgr.

So it apparently is looking at the right place from the getgo and
maybe my problem
is the CDR is too slow to complete it's tasks in the time allowed
by the HA (10 seconds). Yet when the Adaptec is installed and
controlling the 3 HD's, the CDR is on the Symbios as the only
device, it will boot, either of the 2 cd's I've tried.

I have the drives set to sync 40, the cd set at 10 (I've tried all
the settings on the CD). The CD is circa '97, a plextor PX-20TSi.
It's also called a 12/20. I presume that means 12x speed and 20 as
the sync, but maybe it means something else. The only thing I
haven't tried is the HD's set to 10 so that all devices are equal.
Don't want to lose the throughput.

Doesn't appear there is much else I can try, the cd's I'm trying to
boot with are the eCS
beta3 CD and dfs bootable cd. Since I expect hardware to arrive
soon this is not an issue worth fighting, I was merely wondering
why it boots when only the CD is on the
chain but when the HD's are there it doesn't.
