Re: [Bug] MS-DOS 6.0 SYS.COM gives Divide Overflow...

It might not be a PCem bug, since I had the same thing happen on my real PC (the same I'm posting this from right now - I have a smaller 32 MB partition for DOS on another drive).

Re: Build instructions for MinGW?

That's because every variant of MinGW seems to have minor variations with regards to include paths. I wish they decided on one set of include and had all the variants stick to it.

I used the Award 430VX PCI, Pentium 75, 64 MB RAM. Not sure if the choice of board and CPU affects it, but it might.

Use the SYS.COM I linked you to, not the regular MS-DOS 6.0 SYS.COM which does work.

Re: [Bug] Time sync problem

- basic2004: Some BIOS'es consider a year such as 2017 as invalid, and default to 1980-01-01 when they detect it. Make sure to test on other boards as well to exclude such a possibility.

There definitely is an issue in the emulator, as PCem is quieter than DOSBox.

[Bug] MS-DOS 6.0 SYS.COM gives Divide Overflow...

Basically, have it transfer files from a drive or directory where there are the relevant system files, to C:. It will give divide overflow. Edit: It specifically happens with the SYS.COM of MS-DOS 6.0 OEMBase which differs from that of regular MS-DOS 6.0. Download link (SYS.COM only, not the full DO...

Re: Issues with EGA emulation

It's not the emulation that's broken per se but the IBM EGA BIOS that does weird things to probe the card. I have tried implementing the Chips & Technology SuperEGA (with its own BIOS) on top of the same EGA emulation code, and it doesn't have the same problem.

But the Mach64 VT2 BIOS does have VBE 2.0, even better than your Virge's (LBA 2 finds the VBE 2.0 palette call on the Mach64 VT2 but not on that ViRGE).

It could be a bug specific to the ATi Mach64 VT2 emulation as that's the card on which the bug was reported.

I notice that the MT-32 emulation appears to be based on 86Box's MPU-401 intelligent mode emulation (which is in turn ported from DOSBox). I'm going to look into porting it over to 86Box, as it's makes the MIDI code less platform-dependent, and adds a way to use MIDI without directly talking to a ho...

[Bug] Configuration manager doesn't work correctly

I click New, I see the configuration dialog, I click OK, then I'm back in the configuration manager, with nothing on the list, so I can't go further. And when I close the configuration manager by clicking on the X, PCem crashes.
