A few pc-task questions

[fishy_fiz]

Can anyone tell me please how to mount a cdrom inside pc-task. Both for use with DOS, and to be able to set cdrom as boot device (I assume this requires use of an external bios?).
I have no floppy drive, so installing software has been a little bit tedious.

Im also curious if anyone can tell me if there's likely to be much incompatibility with later dos games when using ms-dos4? There's been quite a bit of software that doesnt work that Im sure I used to use last I played with pc-task (which was some years ago). I had a hardfile with msdos6.22 on it back then though.

Thanks in advance.

Ive made some progress. I installed pctcdrom.sys and have it mounting when dos starts up, but trying to use the cd-drive just gives me the message, "cdrom not high sierra or iso-9660 format".
Any help would be greatly appreciated.

The problem with that though is that I cant install freedos without a cdrom being mounted.

To make things a little trickier again I have no floppy drive.
