Expires: References: Sender: Reply-To: fox@bek-mc.UUCP (Jim Fox) Followup-To: Distribution: world Organization: California Institute of Technology Keywords: AT Bridgeboard, Troubles I have got a problem and I need help as soon as I can get it. This is specifically aimed at CATS, but anyone is welcome to respond. I have convinced a local (Los Angeles area) retailer to loan my place of employment an A2000, with an AT Bridgeboard in it. The Amiga side works fine, The Bridgeboard doesn't. The reason for the loan is to test some in-house software/hardware with the AT CPU, and see if we can develop a hybrid system using the amiga to network to a mainframe and the AT to do data acqusition. Without the AT functional the reason for the loan is moot, and the chances of our getting such a system are close to nil. So, I need help fast in getting the bridgeboard problems fixed. The retailer is not much help, they don't understand the IBM applications, they are also over an hours drive away, so it is not a simple matter to arrange a swap. Here is the problem, when I open the PC window, it boots the first time, but won't let me boot the color window equivalent to the IBM CGA device. The dealer did not load all the MS-DOS commands onto the harddisk so I don't have a "mode" command to change from mono to color. I can read a disk once, then one of a number of errors happens, either it tells me disk 0 configuration is wrong, or it writes junk to the screen and hangs, or it tells me "keyboard error 51". Periodically it also says " Parity error on main circuit board". It then will try to reboot, it will then repeat these errors, or it will hang partway into the boot sequence and not go anywhere. I can usually reboot the whole machine with the Amiga reboot sequence, but the bridgeboard is still hung. Checking inside the machine I have found that connector J14 (the video connector) lacks a jumper, which could explain the CGA problems. I tried to wire wrap the two pins for color togther with wire, but it doesn't seem to help. Is there anything else I can do or check? I have worked long and hard to get this opportunity to demo the Amiga here and I don't want it ruined by something stupid like somebody not configuring the board correctly. I am not sure if my work phone # is in my .signature file, I will include it here, but please only call if you really have something useful to suggest. Is anyone at CATS listening???
