I had similar problems, which cleared up when I upgraded to linload 1.3.
The older versions of linload did tell Milo that I had 88M, but for some reason
it didn't work right. However, if I *manually* told Milo that I had only 80M
or 87M everything was OK. But with linload 1.3 I can use the full 88M. In
fact, now if I tell Milo I only have 87M it *doesn't* work. But I don't
really care.

As Wolfgang pointed out (and as the drool-proof paper that came with the UDB
said), the 12MB SIMMs should only be used in the first bank; otherwise they
are only recognized as 8MB SIMMs.

Cheers,
Eric
