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.

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

Re: The sound is silent
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.

Re: [Bug] Warcraft 2 displays nothing
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).

Re: [Bug] Warcraft 2 displays nothing
It could be a bug specific to the ATi Mach64 VT2 emulation as that's the card on which the bug was reported.

Re: [Patch]Memory setting patch
This is what happens when I apply a commit from Sarah the wrong way (by making all AT+IDE boards use at_ide_init()) and then apply this commit here. So yeah, I apologize for the false report, it's just a case of situation normal: I messed up. :p

Re: [Linux] GUI discussion
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.
