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

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. //daniel on autopilot in paradise \X/ powered by intel and motorola

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.
