Dropping an install on a fujitsu b142

[Azeitonense]

I have a fujitsu b142 in not so bad shape, except for the fact it doesn't come with any drives. no floppy. no cd. it does have USB, but I can't boot from that.
Old BIOS...

I'd like to know if it's possible to "drop" an install plugging the HDD from the lappy directly to a USB on my desktop. and how to do it...

It's above my knowledge league... I haven't even installed OpenBSD yet...

Last thing I could find installed on this laptop series is suse 9.2, but the guy had a usb cd drive. Since I don't fancy Suse I thought maybe OpenBSD could be a nice experience.

The thing only has 96MB so I wasn't really thinking of GUI, mostly command...
Just a few tools for reading and editing text files of various forms and maybe a music player...

PS: I might be able to get net unto the bugger, though it might be tricky...
It doesn't boot from net either..

I don't know what to call this kind of install, so i'm a little limited as to what I search for. Flame on!
