[comp.sys.amiga] Sidecar Memory Weirdness

tubman@sask.UUCP (Jim Tubman) (05/31/88)

In brief: My father cannot get his Sidecar to recognise all the memory that
it contains, no matter how we set the DIP switches and jumpers.

He has an Amiga 1000 with an internal memory expansion (to 1.5 meg) and a
Sidecar attached.  The Sidecar has 512K on the main board and a hard disk
card added, partitioned between the Amiga and the Sidecar.

Right now, the Sidecar seems to think that it only has 256K of memory, if
the figure returned by CHKDSK and the failure to load certain programs can
be construed as valid evidence.  However, the Norton Utilities SI program
indicates that it finds two blocks of approximately 256K of memory.

Yes, we read the Sidecar manual.  Yes, we know about the two sets of DIP
switches and the jumpers.  Yes, we set them according to what the manual
says they should be.  We have also tried other settings just to see what
would happen.  When we do that, CHKDSK always says we have 256K, but
Norton's SI gives wildly different answers.

I am beginning to suspect that the Sidecar manual is not telling the whole
story.  Dad has taken the whole setup to his dealer (a 60 mile drive, by the
way) to see what they can do, but they know zippola about about the problem
(which is not too surprising).  Can someone out there on the net give us a
hand?
