^^ Haven't tried it yet, I'm still trying to get those keyboard controllers. I don't want to pull apart the cacheless wonder as I have it set up & am using it at the moment. (The new ET4000 helped a lot.)

^^ MS-DOS 6.22 isn't the right DOS for this. It was never designed for modern hardware and I'm kinda surprised you even got it to boot. FreeDOS *is* designed to run on modern hardware which is why it was painless to set up, I had no trouble formatting the drive & making it bootable (I used FAT32) …

Mine's a 1.66 Core Duo although it shouldn't matter as they're all the same logic board, including the Core 2 models (there was an EFI update between the 2006es & 2007s.) All Intel-based Minis have BIOS emulation, but they need to be able to boot an MBR disk as AFAIK FreeDOS doesn't support GPT. You …

^^ Interesting, although the discussion in the thread is about using it to run DOSBox under DOS with sound support, so it's still not a "native" way to run DOS stuff on HDA or AC97. Incidentally, to finally follow up on this thread, I do have FreeDOS running on one of my Minis. The way you do it is …

I have an AWE64 Gold and a PAS16 that are dead - would very much love for either of those to work. One 8MB Voodoo2 with some texture memory corruption and my Banshee seems a bit flakey although it does generally work. The power supply "board" in my G4 Cube needs re-capping because of course it needs …

that is a beastly card. I *just* put one on ebay. :P Your has the XL rom so it will be more compatible with MCA/CGA/EGA titles. The manuals say 100% but nothing is ever 100% compatibility. Awesome! it's in great shape too, super excited to give it a try. :) Did you still need the ROM dump you were …

Picked up a new video card for my 386 project. This sat on Ebay for weeks, advertised as tested & working, with a $39 BIN and cheap-ish 'domestic' (for me) shipping, so I finally bit. ts1.jpg A little more than I usually spend on retro gear, but damnit, it's an ET4000. Hopefully this will improve my …

I'm using a CF card for storage on my 386, I ended up running IDE-Diag as suggested here to get the CHS parameters and set it up manually using those. It works fine, and seems totally consistent. No data corruption or issues so far. Boot from a floppy with all hard drives set to "none", then run …

The board on the right is, to borrow Phil's phrase, quite frankly gorgeous. :P It’s this deep coffee color which doesn't come across in the pics, with striking gold PCB traces in a mostly-planar vertical layout. It seriously looks like ‘80s cyberpunk art. Or I’m just a dork. 01.jpg It seems to have …

^^ I would have thought it'd be CPU limited due to geometry calculation, etc. The Trident card is an 8900cl (although DIAG identifies it as a 9000 for some reason) and configured for 0 WS memory, but I actually think that it's overdriving the VRAM as I get graphical glitches in some stuff. (I didn't …

Considering the fact, that a DX40 barely runs Doom playable (low res, low detail) you should probably adjust your expectations on what your DX25 can achieve in Doom, especially when it comes to high detail and full res. Well, I'm expecting more than 1.1 FPS to be honest. I only got 4.6 FPS on the …

Yes, it's ANOTHER "tune up my 386" thread. We've got 3 going on the first page now? L0L. My DX25 seems too slow and flakey, so I've been trying to get it to perform a bit better. Some stuff seems to run fine, other stuff terribly. For the recoerd it gets about 18FPS in Wolf3D but only 1 FPS(!) in …

I'll give it a try too, I've got it on a 386DX and a P233MMX so it might be useful to see if they give the same result. BTW please please please call your emulator "Lemulator." Just saying.
