Most systems can also safely add I=B000-B7FF unless you are using a monochrome display adapter or Hercules card.

While UMBSIS works, I found I could get even more UMB space with this old version of URAM, https://www.vogons.org/viewtopic.php?p=260742#p260742 Other useful utils for saving even more memory: XMGR as a replacement for HIMEM, XDVD2 as a replacement for VIDECDD, JEMM386 as a replacement for EMM386, …

Cool setup. You could also add either a MDA or Hercules card and get 4 video cards in the same 386 system. Just a crazy thought.

If it doesn't have to be 1993, the QD6580 is a nice card if you can find it and it is supported by XTIDE so it can support larger drives that older BIOSes can't. http://retropc.sk/obrazky/radic/qdi/QD6580vlb.jpg

Yeah, i have a new design on draft for 1 year but didnt order it yet. it supports auto detection as lpt port so debug is no longer needed and also auto stereo mono switching. No there is no shop to buy it. I also didnt upload the files to github yet. i was just too lazy, eager to do other stuff :-) …

faster L2 cache chips than the available 10ns ones Where are you sourcing your cache chips from? All the 128K x 8 chips I've tried faster than 15ns didn't actually perform any better and seemed to be fake/remarked chips. Shady Chinese fly-by-night sources. As in alibaba or ebay or other?

Re: What mounting screws for older PC/XT/AT power supply?
Posted on 2022-08-23, 03:29
I would expect 6-32 like the screws used on the isa cards. Maybe unscrew one of the screws on the PSU used on the inside to use as a reference it likely is the same size.

Like Shponglefan said I like the Behringer RX1602 because of the individual mute buttons. One note though, you can remove the rackmount brackets but it leaves an open hole on both sides.

Absolutely amazing work!! The TB60XG worked right away with no noticable issues. And because of the great design it has plenty of clearance with the other cards in my system. Thank you so much Tiido!
Re: XMGR and HimemX causing system freeze

Yes, with EMM386 and XMGR's in this configuration there is no signs of issue, but drawback is the CPU goes into protected mode. So only XMGR loaded twice, together with EMM386 or single XMGR /B /N24 are working correctly when DOS is in HMA. Yeah if you want to stay in real mode I'm not sure you …
