Emulator hangs when install Windows 3.1

[OldMadMan]

I've compiled Tsugaru to High-Fidelity mode using cmake under Windows, when install Windows 3.1, Just at the last moment before the installer will enter the GUI stage, one of the following two errors will occur:

The first klnd of error is:

Write to CRTC-HST register. VM Aborted!

Is there any solution to this problem at present? Thank you so much.

Thanks! I look into it!

Hi,

Thank you again for helping me the investigation! Looks like a table that is part of WIFEMAN.DLL is corrupted after loaded to the memory, or while being loaded to the memory. I first want to confirm that the table is corrupted, also want to know where in the physical memory the table is loaded.

Can you try BRKON FOPEN WIFEMAN.DLL (Wait until stop) RUN 011F:00001660 (Wait until stop) then:

BPPC 011F:00001AD5 2 RUN

wait until stop and:

MEMDUMP 247:1032 8 36 ADTR 247:1032

? Thank you very much!

Actually you can have my set and see the result yourself, it'd be forever asking and replying just for certain commands...download this and run the .bat Feel free to tell me anything helpful, thanks. :)

[captainys]

Thanks! I almost pin-pointed the source. I'm 99% sure it was my DMAC implementation. I'll let you know.

[captainys]

Hi,

Looks like it's not my problem. Windows 3.1 L10's problem. If you reduce your RAM size to 16MB, it should start.

Here's what's happening. Windows tries to load WIFEMAN.DLL to to physical address 012352C0H. However, Windows's SCSI driver only writes low 3-bytes of the physical address to DMAC. Therefore, the file is loaded to physical address 002352C0H instead of 012352C0H.

The reason why I say it is Windows problem is how it is writing to the DMAC address. Windows's SCSI driver is doing:

0028:800164DA EE OUT DX,AL 0028:800164DA Write IO8:[00A6] 23(DMAC_ADDRESS_MIDHIGH)

It is supposed to use OUT DX,AX, or write to DMAC-address high-byte separately. Neither is happening.

If you limit the memory size to 16MB, RAM does not extend to that high physical address. Therefore, the highest-byte is not required.

16MB was luxury, and 32MB was unthinkable back then :-)

Thank you very much for your tremendous help!

[qazmko1029]

OK I'll momorize it, thanks troubleshooting. Next should be win3.0 L14, the problem in latest commit just shows the same as before, i have changed memsize to 16mb and nothing changed, continue the topic or stop here?

[captainys]

This thread got quite long. Also the title of this thread says Windows 3.1, which I believe is now pretty well supported.

Let's make it another thread. Can you create one? Windows 3.0 must be full of 80286. Probably I am not implementing something related to 80286 correctly.
