Yes, the AUTOEXEC route is the best, if your mobo boots that far with what BIOS set the DLC to, since some device drivers might get confused if the cache is enabled too early. For your mobo I would use these settings: * FLUSH and KEN off, BARB enabled (BARB is not an input, as such, more like a …

For your mobo I would use these settings: * FLUSH and KEN off, BARB enabled (BARB is not an input, as such, more like a method that uses HOLD to detect DMA cycles) * A20M input enabled, workaround (non-cacheable first 64k of each 1M segment) disabled * L1 enabled in CR0, obviously * exclusion zones …

I also went ahead and installed an SB16 I had laying around last night. Everything went well but during the self-test it complained about thd 16-bit DMA. Played all sounds fine, though. This doesn't have anything to do with the L1, does it? Just covering my bases. Try running any benchmark (3dbench, …

Your motherboard is from 1992. So not an early model. If it doesn't have option for L1 cache, you can always enable it via software. Otherwise DLC is drop in replacement and should work out of the box - usually no need to change any jumpers. Your last post and BIOS screenshots show Internal cache …

The only possible outcomes in my mind are: 1. my board is very early and does not correctly support Cyrix chips, which is why it's totally unmarked This is most likely the case. In my experience the BIOS usually has some options for DLC chips but the mobo doesn't support that in HW. If the BIOS is …

I think A20M# should be connected to the keyboard controller (A20 gate). I've just put everything together and booted with the jumper set to 2,3 (and all of the HIMEM switches removed). The system boots just like if the jumper were left open. No HIMEM error, but the Cyrix tool reports the A20 lines …

This is Camelia. She's a 386 PC I bought on ebay a few weeks back. The entire system seems to have initially been put together by an OEM called NCI. Every part inside had "NCI" warranty stickers and that badge in front seems to have a model name too (NCI Medalist 386). Everything has a sticker. 4 of …
