So I picked up a nice little Socket 7 PCI/ISA mobo with a Pentium 120 in it from liqmat's giveaway a while back, and I've finally gotten around to hooking it all up and getting a nice DOS/WfW setup going (tried Win95, but either it doesn't like the chipset or it's even crashier than I remembered...!) I'm enjoying having a play around with building a fairly maxed-out mid-'90s system after mostly sticking with 386 or earlier when doing DOS boxen in the past, but I'm a bit stumped on one particular aspect.
The board I'm using is a Chaintech 5SEM, based on the SiS 5511/5512/5513 chipset, and unfortunately the only documentation I can find anywhere online is a single-page jumper-guide PDF. Between that and the information silk-screened on the board, I've been able to determine that it supports a maximum of 1MB L2 cache, and I've lined up the appropriate bits for filling that out. However, what I don't know is what the maximum cacheable RAM is; it's nowhere in the jumper guide and not stated in the BIOS setup screen. posts on VOGONS and the like about similar boards indicate a limit of anywhere from 64MB to 256MB for 1MB cache, but this is only for similar boards from the same era; I can't find anything specifically relating to either this board or even just this chipset.
Is there a way to determine this without having the manufacturer's word for it, other than just popping in more and more RAM until it seems to take a speed hit?
