#A20286 BB
4 messages in this thread
HELP! I have a 2286 bridge board that I can not get to run. I bought
it used ,and the guy said it worked when they had it, but he did not
send me the battery for it (I was told that it should still boot, by
an independent person) My old 2088 BB still works, but the new one
tells me it cannot open the Janus library!! Then I reinserted my
2088, and it had trouble booting, it could not finde the C: drive and
auto boot until I rebooted it a couple of times. I do have a VXL-30
accelartor, but it is working with the 2088, although I have to
warmboot the Amiga after turning it on to get the whole system up and
running. I don't know if it is related, but I do have a strange
problem with my Amiga serial port, it wont run my Modem (I am on the
old 2088BB right now). I tried swapping the CIA chips, but still no
go… the printer does work however on the parrell port. Any help
would be appreciated since there are no dealers that I know of in
Charlotte NC! Thanks.
Maybe I can help you?
You have nearly the same problems as I had with my own BB! Mine is
working now (usually), so I would like to give you some hints and make you
some proposals:
-The BB _will_ work even without the battery, this is right. The 2286 and
above do have a setup-program in their BIOS-ROM, without the battery it
will ask you for the kind of diskdrives, RAM-size, time & date, etc.
-The "janus setup failure" is a bug, can be killed with some extra lines
in your Startup-Sequence. For me it worked in this way:
;Start
CPU >nil: NOCACHE NOBURST ;disables cache and burst-mode
Assign PC: sys:PC ;I assume you have the PC-directory there
PC:PCHard ;this is it! a RESET for the PC just now!
Run >nil: BindDrivers ;you should let this line here… Wait 1
; ;a little break. Amiga seems to need it,
; ;I have tested it.
;__________________________________________
;Your own Startup-Sequence must follow now.
I'd like to thank now all the pioneers here and at other places, who had
worked on this problem too, and were talking about! You helped me a lot!
Before change, your 2286 will recognize the janus.library in 1 of 10 cases
and boot even if you did _not_ change your Startup-Seq. Maybe it happened
to you already. As I understand, this even happened with your 2088 (same
happened to me!) after you had put it in again.
After change, the BB will mostly boot in the right way; but from time to
time this procedure will fail. So this is not a 100%-solution: say 95%.
-In the beginning of the Startup-Sequence cpu-caches and burstmodes have
been switched off. Please add a line in the user-startup:
CPU CACHE BURST
Now the message about the janus.library should no longer appear while
starting the BB. When you start the 2286 with PCMono now, either the line
"bootdisk failure" will be presented to you, or the SETUP-menu, similar to
the CMOS-Setup on PC's. Assuming that you will use a harddiskfile for your
PC, you should make an entry for c: that it is _not present_.
If you meet a "Bootdisk failure"-message, do a ctrl-alt-del, shortly after
this a ctrl-alt-esc, and hold the keys down for a while. This is the grip
for the SETUP.
When you leave the SETUP-menu (use the save-option), the BB should boot
now from your harddiskfile.
This works for me in an A2000 with a 68030+4MB (2630), but I cannot
guarantee it for a VXL-30 (I have never seen such one)…
…but your serial port needs an urgent repair, I believe. In my own Amiga
and another one, belonging to a friend, I discovered that the line-drivers
were broken, two small chips, 14-pin each, called 1488 and 1489. They are
soldered to the mainboard and hard to change. In your own interest: if you
are not well experienced in electronics, let them change by an experienced
friend or a service! The whole mainboard has to be taken out of the case,
and the chips must be cut out with special pliers – the pins must be
soldered out, and the little holes in the mainboard must be sucked out
with a little vacuumtool. You see, it is complicated, but you should give
it a try. The new chips must not directly be soldered; you can use sockets
on the mainboard.
I had another very funny defect in a connector, it was a broken pin; but
this connector was for the joystick, and I assume that you don't connect
and reconnect your modem so often.
Now I've written quite a lot; but you have such a mean malfunction in your
set, that I simply must try to help you!
By the way, I finally decided to end my only-read-and-download-era (some
people call it lurker-phase) and face the public!
I am typing from germany, this is expensive, but with a little help from
AutoPilot, affordable.
…and if anyone thinks my english is funny, feel free to smile. But give
me a hint.

harry,
I think a lot more of us would be lurkers if it were not for
AutoPilot.
Thanks to Steve A. for a fine piece of software.

Thank You, Thank You, Thank You. I have been trying to get that BB up for some
time, I will give your advice a try and let you know if I succeed. Thanks
again. Gary.
