01 April 1997 I recently upgraded by Gateway 486/DX2 66 EISA from 32MB RAM to 64MB. This caused quite a lot of pain. I have been running WinNT 4 for quite awhile with success. But the pressure was on to get things back together between business trips and USA income tax deadline! The system wiped out the Drive C: which was my boot drive. This is a standard FAT drive. Luckily, I keep my own files on D. But in the EISA machine, I'd recommend you use the ECU/CF utility to adjust the RAM *before* you install the RAM itself. I believe this would have saved me quite a lot of pain and suffering. As it was, I finally had to run FDISK and delete and recreate my primary active partition on the Drive C. Then a reFORMAT and reINSTALL of Windows NT. (This isn't easy since most of my Microsoft-ware is "upgrade", so it looks for previous versions.) Anyway, I'm back up and running. Limping along on an old 486/EISA. Cheers! Byron byron@bellatlantic.net
