Bug in switching CDs

Post by win2kgamer »

I have noticed that when I try to use the "Eject" command from Windows 95 or eject/switch CDs with Daemon Tools (Which I use as the host CD-ROM), some strange things happen in the emulator:

- In Windows NT 3.5x, the guest OS doesn't correctly detect the CD changing and shows the old disc's volume label and a mix of contents between the two discs.
- In Windows 95 OSR2, the guest OS either crashes or displays a blue screen like the images below.

I did find a workaround though: When you are about to switch CDs, set the CD-ROM drive to "Empty" in the Settings menu, switch the disc, then set the CD-ROM back to the host drive you were using.

EDIT: I did manage to reproduce a bluescreen when switching discs, I have attached it below.

EDIT: Forgot to add configuration:

CPU - Intel 486DX4/100
System - Award SiS 496/497
Video - Paradise Bahamas 64 (S3 Vision864)
Cache - A lot
Video Speed - Mid VLB/PCI
Soundcard - Sound Blaster AWE32
Memory - 16MB
PCem version - v9 (Release)
Host OS - Windows 7 Professional x64

I can confirm this happens on my side too, (seems to work OK with a 386 tho, but Win95 doesn't run all that great on a 386).
In DOS it works fine.
