![]() My >CF->IDE->USB, power jury rigged from 9 volt battery. Flashing the harddisk image onto the CF card (Linux) That's it! You're now ready to reset the machine/vm and boot DOS, it will have a nice and familiar C:\> prompt. Then create a basic autoexec.bat with edlin: ![]() (there are two floppies for IBM PC-DOS 3.30 Press CTRL ALT DEL and press A when the XTIDE BIOS info comes up (just press it a lot of times until it says "Booting A" (note, on PCem, you also send CTRL ALT DEL from the menu). They also apply to real harddisks, but you may need additional configuration of the HDD controller and low-level formatting first.Below is (more or less) a transcript of the installation after booting dos.Īt this point, the XTIDE card sees that there is a partition on the CF card and wants to boot it, but it will fail. These steps are the same whether you're installing DOS on PCem with floppy images or on the IBM hardware with floppy disks. Then I installed DOS using the steps described below. With the virtual machine as close to original as I could manage, I went ahead and used PCem to create a 64 MiB harddisk image (type: custom) and booted the IBM PC-DOS floppies in the emulator. Drive 0 Primary Master C: Type: harddrive.I chose the easy way, since I don't have DOS 3.30 floppies, I found the images online, and used PCem. Using an emulator to prepare an image for the CF card After inserting the card, the machine booted and showed the XTIDE Universial BIOS as expected. The card I bought was configured to: BIOS RAM address: 0xCA00 IDE controller base address: 0x300 and Boot driver at 0x80. My unit has two floppy drives, and rather than changing that configuration for a half height MFM drive (which I could have done), I chose to keep both drives in the machine, and install a CF card harddisk emulator instead, this also allows me to conveniently transfer files back and forth between the IBM and a modern computer.
