I have noticed two problems with my A2286. 1. When using Wordperfect,
during the auto-backup-saving of my document, characters are lost
from the keyboard buffer. Does this have to do with #2?
2. The HD emulation is very slow? Would an 8bit hd card for the IBM speed
things up. Would I need 40ms or is 20ms really really much much better.
I am leaving the 16bit slot open for more memory - is this stupid? Should
I put a 16bit HD card there?
I appreciate the time it takes to reply.

Should >I put a 16bit HD card there? problems 1 and 2 are indeed related. there is a hardware fix (lift an IC pin and solder a jumper from it to somplace else). if your bridgeboard is out of warranty, i'll give you the fix. basically, due to incomplete address decoding, when the pc sends the amiga an interrupt (for instance, when it is requesting a disk block from the amiga) it also whacks the keyboard controller (8042) upside the head. this causes two things - if a key is being processed by the 8042, it is lost. this is the "lose keys while fake disk i/o is happening" problem. the other effect is that it causes the 8042 to generate a keyboard interrupt to the 80286, and this unnessary interrupt drastically slows down fake disk i/o. >I appreciate the time it takes to reply. > >-Greg Gibson >gsgi_ltd@troi.cc.rochester.edu --Scotty -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Scott Drysdale Software Engineer Commodore Amiga Inc.

I think most Bridgeboards are out of warranty. Can you publish the fix here since we are a technically sophisticated lot? Thanks! -- Jimmy Liberato liberato@dri.com ...uunet!drivax!liberato
