Thanks for the suggestions.
Jumper 20 is closed on my GVP because I have 4 meg sticks. I noticed that the jumper for DTAK pullup has been wrong on my GVP all these years, so I changed that, but it didn't help WHDLoad.
I found my GVP install disk and the GVP memory test passed.
I originally had one 4 meg simm, and I got 3 additional ones from SoftHut, which were supposed to be compatable.

Too much memory chunks.
Memory needs to be in one contiguous address to WHDload works.
What causes that, and how can it be rectified>?
