I am having trouble using the NI5210 packet driver distributed by
Clarkson on a board that has only 8K on it. The driver fails with
"Timed out while initializing 5210." when I try to load a driver
on a 5210 that either has an empty memory socket or a novell remote
boot prom in it (i.e. 8K RAM only). I have tried this on a few
different machines.
A quick look as the source code (last update 4/27/89) shows that
the driver pokes out 5 words to the upper 8K (a potentially bad
practice if the upper 8k isn't there), but the comments say it
doesn't use it. I could not find any information in the
documentation as to whether the driver was written for a 16k
configuration.
Any help/patches would be appreciated.

The 82586 gets the root of its configuration data structure from a fixed location in memory (the last few bytes). This location changes with the amount of installed memory on cards which allow it, and complicates driver writing. A simple workaround is to change all references to the location at the end of the 16K to a new location the same distance below the end of the 8K. Then, re-size the number of receive buffers and you're on your way. PC/TCP's drivers for the NI5210 do this... James B.
