Need info on a Toshiba 3100e/40

I was just given a 3100e/40 "laptop". It powers up, screen works, goes through bios and then asks for a boot disk. The expansion bay is empty, which is where I assume the hd goes. I tried booting from a DOS 6.22 disk, but it couldn't recognize it. I'm guessing that it's not a 1.44mb drive.....800k perhaps? (It's 3.5") What version of DOS is the latest supported? I would also like any info on the processor, etc. The little beast has one whole meg of ram, so this is truly a power machine......remember when you could fit a word processor into 64k of ram along with Basic? Also, what kind of hd does it support? I'm guessing I'll have to track down a proprietary drive carrier, but does it use ide or is it mfm/rll? Thanks.
