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. -- Chuck Forsberg WA7KGX ...!tektronix!reed!omen!caf Author of YMODEM, ZMODEM, Professional-YAM, ZCOMM, and DSZ Omen Technology Inc "The High Reliability Software" 17505-V NW Sauvie IS RD Portland OR 97231 503-621-3406
