- Not so long ago I went thru several motherboards in search of
- one that operated properly with more than 16MB main memory. I
- never found an ISA board that would pass a through memory test
- program, let alone Unix under load.
-
- I ended up with an EISA motherboard. The EISA motherboard has
- been running ODT with 32 MB for some time.
