I love your work! Thank you first of all for all of this! I would like to see ZModem protocol in the telnet program as well. There are many BBSes, that do not support other protocols for file transfers unfortunately and therefore make the combination with mTCP's telnet program useless for download/ …

Went through my collection of 72pin ram sticks and tested each of them and put stickers on them with the size. No more mysteries about the size of each stick. Total count ~50. Even found 2x32MB 60ns sticks i wasn't aware of, and 16MB 50ns stick that might be handy on some extreme overclocking. 😀

@Tiido, RDOSUMB on SY-25P2 detects it to be with SiS-486 chipset. As the only difference between the N and P variant is VRM, i assume it's the same with SY-25N. I think i did test it without any keyboard controller while trying to read out something from debug card. Only way to get any different …

If your bus is at 33MHz, then to have CPU speed at 133MHz, you need multiplier to be ...? The answer is even written on the box! 4th point.

I've given up on this board. I currently have no ideas what to test further to make sense what is going on. I also just got a similar board with VRM. (SY-25P2) It works and i was able to use 486DX4-100 on it. (With this board in topic, i planned to use 486DX2-66) Therefore i have my 486 completed …

Unfortunately the siv can't load up it's ui on 386dx. It hangs the whole computer. But before it does, it is able to generate the log file, so there you go.

@elianda : thank you for the test, I think there is a way to tell if a 386 is Intel or AMD, if this is the case I'll add a fix. the benchmark is a simple dhrystone/whetstone. AFAI could see, the dhrystone score varies with the cache hierarchy, but not much with memory speed (maybe more on 386 w/o …

At last, i have a 486 VLB system! I was missing a motherboard, but now i got it. So obviously i spent huge amount of my sleeping time this night to build and set it up. During this week, i hope to find time to set it up as a killer win 3.11 machine. (DX4-100MHz, 128MB ram, VLB IO and video, +sound …

I've used both OnTrack and EzDrive and at least the primary partition is available through memory card reader. With EzDrive, extended partions look as if formatted in unknown format. With OnTrack, i don't remember, maybe extended partions did work. But the classic C: drive is accessible on both …
