New hard disks are saved in IMG format though some understanding on disk geometry is needed to articulate the size of the drive you want. Configure Hard Discs – Provides the ability to add/remove a hard disk and CD-ROM drive, reserving drive letters C, D, E, and F for this purpose.Eject Drive A/B – Another two options to simply dismount the floppy disk image that was previously mounted.Drives A and B were traditionally reserved for floppy disk drives. Change Drive A/B – Two options to mount floppy disk images (IMG, IMA, and FDI formats).Ctrl+Alt+Del – As you possibly guessed, it’s the equivalent to pressing the Control, Alt, and Delete keys simultaneously to restart, known as a warm boot.When the emulator restarts it checks that the memory is okay. Hard Reset – The equivalent to physically pressing the reset button on your computer, also known as a cold boot as the computer momentarily has no power.PCem’s menu is rather straightforward, there’s not much to see though some will be further explained later. Here’s a summary of what each option is: It’s just a matter of extracting everything from here into its own folder on your computer. Distributed as simply a ZIP file there’s no installation program whatsoever. The Windows version is apparently more polished. PCem is available for both Windows and Linux, though I’ll be using the Windows version here. Before focussing on how to set up specific operating systems, this will be an introduction on PCem in general based on creating a 386 PC. Granted it’s not immediately obvious to the average Joe setting it up and getting it to work smoothly. For example Oracle’s VirtualBox allows you to change the amount of video memory, but you’re unable to change from one model of video card to another. Usually hypervisors for the most part have rather limited flexibility of the type of hardware that can be emulated. Originally released in 2007 when it was limited to emulating an original IBM XT, PCem now allows for a Pentium PC running Windows 98 or even Windows XP. PCem I personally believe is one of the more interesting hypervisors available to emulate hardware.
