Portable 286, but it was replaced by the more compact Portable II in a redesigned case within a few months. The Portable 286 featured a full-height hard disk, and the options of one half-height floppy drive, two half-height floppy drives, or a half-height floppy drive

Aside from using DOS 1.x, the initial
Portables are similar to the 16 KB – 64 KB models of the IBM PC in that the BIOS was limited to 544 KB of RAM and did not support expansion ROMs, thus making them unable to use
