I got this Intel ram expansion board that came in a 286 above board box but I don't think it's the one that came with the box originally. The manuals show a 16 bit card and layout that looks much different from the one I have here. I tired plugging in it my 5160 but it didn't read it. Does anyone …

Well so far I was able to get the WDXT-Gen2-Plus to read all the hard drives I can actually perform a LLF using g=c800:5, I was using that card on a 486 motherboard it has Super Bios II Rev 1.0 and it seems pretty easy to use it asks me what interleave I want to set the drive to and then asks me if …

I used that cache utility and it says "This machine seems to have one cache? cache is 16kb --199.4 MB/s 5.3 ns/byte (405%) 1.8 clks" "If you think you do have L2 cache, you might have Fake Cache chips" I don't understand why it says that? Here is the updated speedsys with 4.78 http://i636. …

Very mature to judge maturity by the use of emoticons. Sigh. @Turboman: The odd false display was part of the game. Its programmed into the BIOS. It is part of the old PC-CHIPS fraud. If you swap the BIOS with one of another board with the same UMC chipset you will see the correct cache size. There …

Well, I tried jumping it to 256k and the system would not go past the post screen so, I put it back the way it was and it works again so, bank 1 looks to be fake then, it's odd that it displays 256k but is jumped for 128k.

I tried it on the M919 and I get zero ohm all the way across pin to pin all 4 sides. So, I'd assume they are all connected to each other inside at least on that style of chip.

Guys, I did a continuity test that was suggested and found that on all the cache chips the last pin to the bottom row right is the only one that beeps everything else I get a reading and on the Tag chip I get two beeps top side row pin 7 and pin 9 everything else is gives readings. So, this means …

Wow I don't feel as bad knowing that one has actual Cache now, anyone know if it might actually be 256k but was just set up wrong? I mean I could solder jumper pins on for the cache right? or just jumper it correctly?
