I just got a Symbios SYM22801 (53C876-based) card handed to me last week,
and I decided to put it in my machine to replace a less-capable Adaptec
AVA-2904. I've run into an interesting problem. I'm not sure if it's
cabling-related or not, but the cables do seem to make a difference.
Here's how my setup works:
ID 5 ID 6
+-----------------+ +-----------------+
| UMAX scanner |----narrow SCSI---| Archive DDS-1 |
| (Astra 1220S) | | |
+-----------------+---terminator +-----------------+
|
|
CS Electronics 68-pin VHDCI<->50-pin Amphenol cable -->|
|
+----------------------+
| (ext 68-pin) |
| SYM22801 channel B |
| |
| (int 50-pin) |
+----------------------+
|
| ID 4
+----------------------+
| TEAC CD-R55S |
| (terminated) |
+----------------------+
Now, here's the interesting part.
- When I have *only* the external cable connected, the channel works without
errors.
- When I have *only* the CD-R55 connected, it also works fine.
- If I have the external stuff on channel A, and the internal stuff on
channel B (or vice versa), that works.
- However, when I have both connected to channel B, I get this mess:
sym1:4: ERROR (0:48) (2-21-0) (f/35) @ (scriptb 2e8:11000020).
sym1: script cmd = 88080000
sym1: regdump: da 10 80 35 47 0f 04 0a 01 02 00 21 80 01 09 00 00 52 dc 01
08 ff ff ff.
(noperiph:sym1:0:-1:-1): SCSI BUS reset detected.
over and over again, until I reboot the machine. I've not yet tried the old
ncr driver on it. I've tried setting the channel switches to INT50 ON and
HIGH TERM ON, but to no avail.
I could put the CD-R on channel A for now, but when I get a SCSI disk to
go there, I want to reserve channel A for it and other-high speed stuff, and
channel B for the slow things. Any idea what's going on here?
