Re: VHD support

Let's see, 65,535 cylinders, 16 heads and 63 sectors per track, that's actually, 66,059,280 sectors for a maximum total of 33,822,351,360 bytes or almost 31.5 GB which is plenty for a successful Windows 95 OSR2 installation. :)

Re: External USB Floppy Drive

I don't think that PCem has no support for reading physical floppy disks at this time, only physical CDs. If you want to use floppy disk support in a emulated machine that PCem emulates, you can use floppy disk images and be prepared to insert a floppy diskette image when you initalise a hard disk i...

Re: [REQUEST] ATI Graphics Ultra Pro

As far as I know revision builds of v14 is expected to *only* have bugfixes (if any), but no new features and v15 is expected to have a redone dynamic recompiler.

I would strong advise against asking where you can find the SCSI ROMs that you do not legally own. If you have a real ISA, VLB or PCI SCSI adapter and have a dumped a ROM that matches the supported adapters emulated in PCem.

[REQUEST] IBM 8514/A & XGA adapters

When IBM rolled out the Personal System/2 launch models 30, 50, 60 and 80 on April 2, 1987, these models had a integrated VGA chip. When VGA was introduced, IBM also introduced another display adapter, the IBM 8514/A . The 8514/A display adapter offered 640 x 480 pixels @ 256 colours and 1024 x 768 ...

You might also have to use a newer graphics card that supports linear frame buffers.

I get the hang on the same mode on all the Cirruses at least, on the Trio64 (which DOSBox's default is based on) and on interpreter so it doesn't seem to be Trident-specific.
