🤣 I was about to help diagnose this but I just blew up my som-128-ex. Fed it 12v by plugging in a power cable backwards... Ordered another one.

The stock 86duino BIOS also has issues with mice. I assumed it was just because USB mouse support wasn't compiled in but it looks like this may be a problem elsewhere too.

Yeah, those 0603 parts are pretty small. Decent eye sight, a steady hand and a soldering iron with a fine tip is a must. I often use one of those big magnifying glasses with a ring of LEDs encircling the glass, mounted on a flexible arm to make it easier. I'll contact you by email, I'm sure we can …

If the SOM304RD-VI is anything like the SOM-128-EX, it probably has some sort of small eeprom chip soldered on the carrying board. If you've got a programmer with a sop/soic clip attachment, it's possible to do a recovery programming of the original BIOS (save it first, of course) without lifting …

Same result on Windows ME? or it works? Just tried it. Windows ME has the exact same problems loading the driver - but with default Microsoft drivers the speed is MUCH faster than on 95/98(about the same as XP). I think I've just proved that the speed problems aren't caused by inability to load …

That's awesome! Yeah, CGAArt only uses one thread for matching at the moment - doing that on a GPU has been on my list for ages as all the character/attribute combinations could in principle be tested in parallel. Another feature I'd like to implement is temporal error diffusion which would either …

Welp, Do you want me to try and do the backport of XP's atapi.sys driver then? Honestly, I really don't care about the disk performance in Windows 98 :) It works fine in DOS and that's all that matters to me. I'm skeptical that it's even a driver issue at all, really... it needs more diagnosis (for …

Some ideas for your hypothecical WeeCee Max (Ultimate Win98 machine) - The way I see it, weeCee is and will always be a DOS gaming machine, not a Windows one. DOS gaming PCs have totally different requirements to Windows PCs. The Vortex86 just isn't a great platform to run Windows 98 games on - …

@rasteri Have you tried adjusting these settings to see if it helps? Sorry I haven't been home for the last few days, I'll try to get to it soon. I've fiddled with the "Standard IDE Compatible" settings before but it made no difference. Although that was before we had your driver. Not tried the DMA …

I have tried moving all pins on both ic's with a scalpel blade, none are loose. I haven't resoldered them yet though. Yeah the pins on mine were obviously loose, although I did have to look under a loupe to see it properly so maybe you'll see better under a microscope It's very possible that un- …

Yep I had to resolder a bunch of pins on my maxi gamer 3d. I suspect they were never soldered in the first place, just they made enough contact with the pads that it worked for a while.

I wonder if that SOM's SATA will work with rloew's SATA patch? Doesn't even need a patch, the BIOS (at least in the Vortex86DX3) does IDE emulation. If you're feeling up to it, could you try out the VIA VT6421A chip? It should be really compatible even with win3.1 assuming it can work with the …

@rasteri So, no chance for any hardware revisions? or experiments? Well down the line I might consider doing a "weecee max" or something that had some extra stuff. But probably not with the 86DX - there are other Vortex86 SoMs that have inbuilt SATA/HDMI and other fun stuff that I've been playing …

1x additional USB port, I find that some USB hubs interfere with USB booting, but I also like to use a USB Mouse/KB too (hub is not an issue for these). Being able to use USB Mouse/KB and boot off of USB at the same time would be nice. 1x RS-232 Serial Port for remote debugging - although this …
