OK, I now know why OS/2 Warp is only seeing 48MB. It's because the computer things it's has 16MB in each of the three banks when in reality it has 64MB per bank, for a total of 192MB (in upgrading I discovered that it didn't have the 48MB I thought was in it, it had 112MB). According to the manuals this system supports 32MB EDO SIMMs, which is what I'm using in all three banks. Any idea how to convince it that it has them instead of 8MB ones (it things it has 1 bank of ECC, and two of EDO). What can I say, I just got the system recently and it's the first PPro I've had, and the first system with EDO RAM. Zane -- | Zane H.
