Re: Future graphics card emulation

Don't forget the Sigma Designs Imaging Systems ƒ/64 (powered by the WEITEK Power 9100 graphics chip), which (apart from the ATi Mach64) is the only other way to get 4MB of VRAM recognized out of the box by OS/2 Warp.
Here's the datasheet for the WEITEK Power 9100 graphics chip.

Re: [FEATURE REQUEST] Removable Media Drive Emulation Overhaul

As a self-imposed challenge, I eject first... because on a real PC only one medium per drive can be inside.

Why on earth would you want this?
Because that's the way a real floppy drive works.

[FEATURE REQUEST] Removable Media Drive Emulation Overhaul

For floppy drives, PCem should allow mounting images only when the drive is empty.
But as for optical drives, PCem should emulate their tray states (and allow mounting/unmounting images only with the tray ejected).

Just like a real PC!

Re: Speed timings for emulated hard disks

I would like to see this feature on PCem v17!
Also, the most common HDD speeds are 3600, 7200, 10000 and 15000 RPM.

That PCI SCSI adapter from Adaptec (apparently) introduced the ability to boot from CD-ROMs.

(REQUEST) Wave Blaster and Compatible Daughterboard Emulation

The Sound Blaster 16 and Sound Blaster AWE32 need it to produce more realistic instrumental music than the on-board Yamaha OPL3 chip.

Is it superior to any Intel 430xx?
Yes, since it supports VLB.

(FEATURE REQUEST) DFI 586OP Emulation

Hello Sarah! (Formerly known as Tom?)

The title motherboard seems rare, as it had an OPTi Python chipset documented here.
However; sice PCem v13 is feature frozen, we shall save it for one of the next versions.

Thank you very much and keep up the good work!

Where do you observe that?

Sorry about that, but when I try to eject the CD-ROM drive on PCem with Windows 2000 installed (by right clicking the drive and choosing "Eject"), nothing happens (unlike a real PC).

Re: [PATCH] CD-ROM improvements

There should be a command to open/close the emulated CD drive tray on PCem, but changing discs will be impossible if it's closed.

Regarding Award BIOS boot beep

The faster the emulated processor,
the shorter will be the Award BIOS boot beep on PCem.

PCem finally has code to emulate Pentium processors.
TomWalker, thank you for making this program!
It's great, so keep it up.
However, it shouldn't use the host OS date/time, since beta guest OSes may not work on PCem!

Emulation of Pentium I processors!?

Are there any plans to make Pentium I processors emulable on PCem?
Sorry for requesting such a feature, but emulability of IDT WinChips is already a reality.
TomWalker, thank you for all your hard work!
It's really great, so keep it up.
