In my case, I'm not using any logical partitions at all. I remember with at least some of the early controllers you could get into DEBUG and do a "G=C800:5" and it would run a hard drive setup program. Everything is in the MFM/RLL controller and it never shows you what it's doing. Thanks for all the testing! In the XT class machines, there is no BIOS setup to "memorize" the disk geometries like there is with newer BIOSs. Hdd_fn = D:\bretj\Documents\Virtual Machines\VHDs\Multi-DOS Common Boot 20MB Type 2.vhd Hdc_fn = D:\bretj\Documents\Virtual Machines\VHDs\Multi-DOS 20MB Type 2.vhd Here's the configuration file (of course, I eject the floppy when I try to boot from the hard drive):ĭisc_a = D:\bretj\Documents\Virtual Machines\Floppy Boot Images\MS-DOS 3.20 360.img I use the exact same VHD for other machine configurations in PCem (from a 286 on up) and also in other emulators, so I know it's a valid boot image. I just get a "." appearing in the upper left corner of the window and then nothing else happens. I can get the XT to boot from a floppy and see the hard drive just fine so I know it's mounting correctly, but for some reason it won't boot. I'm setting up several different machines and different versions of DOS with PCem v17 under Windows 10, but can't can't get the 8088/XT to boot from a hard drive (VHD).
