This is, of course not optimal, but it should work. I had a previous 8M SIMM (70ns) and I added two 60ns (8M each). The system board has 4M-70ns so this totals 28M (all is parity memory). The BIOS detects and checks all the memory without problem, but every operating systems has a different idea of the memory available: OS/2 Warp 3 reports 28M M$-Windows 95 26M FreeBSD 2.2.5R 16M I have tried changing the order of the SIMMs with no change. Any comments ? :-) cheers, Pedro. == --- FreeBSD: The Power to Serve ! http://www.FreeBSD.org _________________________________________________________ DO YOU YAHOO!?
