This occurs in all PS/2 machines with the IBM ESDI controller. DOS 3.3's FDISK also does not detect the harddrive with this controller.

My questions about PCem

Hi all!

I have some questions here.

1 - What is the release date for v16?

2 - Are PCJr carts supported? I have River Raid (an .JRC file) for the IBM PCjr, so how can I load it on PCem?

3 - The Matrox Mystique is complete or not?

Re: Some weird things in PCem...

Anyway I don't know if this occurs because of the CDROM speed, probably a bug in PCem. I would like to know ...

Yes, I know. I'm using only for testing and not for general use. Perhaps the Matrox Mystique won't contain any display bugs, like the Stealth 3D 2000, S3 Virge DX and S3 Trio64 have.

Thank you. But I do have original disks, I only have floppy images of MS-DOS 3.20 (Amstrad) and GEM 2.1.

What HDD controller I should select in my configuration? I already had created my PC1512 config.
