PSW bug - present in all versions of fw. In all interrupt handlers, PSW is not pushed and popped to/from stack. Any executing commands, which have JC, JNC, JZ, JNZ in code path, or any usage of carry (rrc, rlc, e.t.c.) can be affected. In typical (classic) SB usage scenarios, this should not be an …
Re: Microsoft PS/2 to serial pinout?
Posted on 2023-10-10, 18:18
Huh, different again from the pinout I got working. Now I'm wondering if this was yet another design, or if I just got somehow lucky. I didn't use DB9 pin 6 at all, maybe it's used as some sort of loopback for the driver? Although Win98 auto-detected the mouse fine with how I wired it up. And I …

Does the third "4.13 maelgrum" release fix all known bugs so far in 4.13? I'm gonna burn it to all my cards and call it done if yes. I've given up on seeing single cycle DMA get fixed in firmware, don't think it's possible These are the fixes that are out there? v413-8k_4ca3dca8_patch3 - Fixed …

Yep, that chip... I made a mistake because one had BIOS written on it. Jet's fault LOL Basically it won't work or work incorrectly but not fry anything? Then I should look for datasheets and compare. That's correct, they are all pin/electrically compatible, so no possibility of damage. Just stick …

I have several adapters, but none of them are marked. I also don't have a microsoft serial compatible mouse to test with. If you can identify a defining characteristic of the MS one I can see if I have it From what I can find on the web, the MS adapter for this (and similar era) mouse will have …

Why can't this guy (or anyone) just want to have the best of X for his system without 20 people shitting on his thread asking why it matters and demanding he justify his desire? I want the best network card because I want it. I want the best storage subsystem because I want it. Objectively almost …
