It's an Intel AboveBoard 286. The docs state that it's an EMM board. With it you can add up to 2MB of EMM to your 286 or 8088(!). It's a fullsized ISA board and it looks like mine has 2MB on it. I'd like to use it as a ram disk for FreeBSD, to have 2MB of fast swap space. But for that I'll have to write a device driver. 1) Has anyone heard of this board? Does anyone use it? Is there source of a device driver for it? (Any system) 2) Can a non-kernel process address the ISA memory space? To experiment I'd like to be able to write to it's addresses without rebuilding the kernel. 3) Does anyone have a pointer into Intel Corp. to someone who can give me more info or even specs of this board? The docs tell me that the board can be used to supply _conventional_ memory via a setup program. That's odd. I didn't think an XT could address memory via the ISA bus? Or can it? Thanks in advance for any information.
