Well, the status of the chip can be easily determined by booting the machine and seeing if you still see that 'P' at the right end of the string at the bottom, as that comes from the keyboard controller (command 0xA1). If it's there, then the keyboard controller is working and the problem is …

It's fine to put them here, just put them into a .RAR or something and they can be attached easily. And sad to hear that about your 286.

Oh, thank you very much! Yes, I meant the 386SX. Also, I have now attached JETKEY.COM (in it own .RAR on this post) that does the excat same (except the file is named JETKEY.BIN), but saves the output file after every keyboard controller command run, just in case AMIKEY.COM ends up in a hang or …

I see, but that's missing the final character that only appears on the POST screen, and is obtained by running keyboard controller command 0xA1 (AMI get controller version), and that's what I need, in order to know which AMI keyboard controller version that copyright string belongs to.

Hello an info on the fly. I restarted a 386SX and I was wondering: can your program work? I remember that it goes on the 386 but I don't know if it works on the 386SX, this being quite similar to a 286 (ie 16 bit instead of the 32 of the 386). If it is possible I would like to try it these days, I …

You just need to go to Settings and choose an emulated machine that's ACPI-capable. On PCem, that's going to be that lonely Gigabyte with 440BX and the one VIA Super Socket 7 machine, but on 86Box, you have a wider selection of machines with ACPI, including for Pentium, eg. the NuPro with 430TX.

The real 5170 isn't going to override whatever the diagnostics diskette writes there with date and time from somewhere else, so it's very unlikely the diagnostics diskette is going to be reading that value from the century register at that point. I also haven't tried forcing, say, a value of 19h (ie …

I stand corrected, that's not an 82C311 but an 82C711, which is an I/O chip that, for some reason, uses the same protocol as SMC. This means the MG-9275 remains a mystery - someone in this thread probed the VL82C330 ID registers on it and got FF, so it must be something else. The question is what.

Huh, according to the datasheet it should be F2-F3. Don't know what else to do to detect it if the result isn't as described. Here a new build: - Disabled AHA-1540 detection again. - Automatic exclusion of SIO check for this board. You might test with 8042 and SIO check enabled - Added FPU …

If the disk is ejected during seeking, the seek would complete without issues (the drive's step motor is still going to move the head), but the read command is not going obtain any data from the drive, and therefore most likely time out, which would cause DOS to report "Not ready reading drive A:". …

I also ended using 86box over PCEm for the better interface, but v17 brings optimizations that make it run much faster, and don't seem to be applied on current 86box builds. On my PC 86box can run POD on Windows 98 without CD music skipping on a P166MMX... PCEm v17 can do it on a P233MMX. Same with …
