Re: 430VX and Win98/ME now crashes PCem

I've finally been able to reproduce this! Fix in rev 1019.

For the record, what is happening is that an unidentified driver (possibly for a tape streamer?) is executing commands on a non-existent drive 3, and does not handle unexpected FDC behaviour very well.

On a side note, I don't know if you have some reference for the ATAPI commands.
Numerous - the official ATA/ATAPI specs are freely available, and much more reliable than relying on a random wiki.

Re: How music is emulated in PCem (MIDI)

Do you have AWE32 selected for both sound effects and music in Duke's setup? I know there's a bug there, setting sound effects to SB16 will work around it. The 'MIDI out device' setting is for General MIDI output via port 0x330 only. PCem will emulate the real AWE32 synth for games that directly sup...

The crash is gone now. However the Win98SE guest now has a hang during boot. There's a lot of FIFO is now 01, threshold is 10 onesec in the log Disabling the FDC also gets past this.

That's no use I'm afraid - the stack appears to be totally corrupted :(

Re: 430VX and Win98/ME now crashes PCem

Thanks for sending me the binary. I'm guessing though that it isn't the same build that you generated the above backtrace with, as none of the addresses match. Could you post a backtrace from the binary you've sent me?

Re: 430VX and Win98/ME now crashes PCem

That looks like a potentially useful backtrace; pity there aren't any symbols!

If you can't get a build with symbols, could you send me the binary that generated that backtrace? I may be able to figure out what's going on from that.

Re: 430VX and Win98/ME now crashes PCem

Does GDB point to anything helpful?

(Starting PCem through GDB hasn't worked for me since the new GUI got merged. If this also causes problems, try starting the emulator, then attaching GDB to it with --pid)

Re: 430VX and Win98/ME now crashes PCem

Still can't reproduce this.

Does the emulator itself crash, or does Windows 98/ME crash?

Have you tried doing a clean build?

Can you attach the CMOS RAM file you're using?

Did you test it with stock PCem v13.1? There was a fix on Jan 16 that fixes CD Audio, but that was later than 13.1 was released
That was only for SCSI drives. IDE should be unaffected.
