Ok, here goes. Initially there was no instance of fdisk on the machine, so I did a format c: (thinking I would do like you said and boot off a floppy and install everything from there.
Then, I found the CDROM drivers, installed them, but the machine does not see the CDROM as a drive, so I cannot install from it. I thought I could hook up an external through the PCMCIA slot. So I installed the drivers for the external, and the machine errored on boot sayiing it was trying to load the CDROM drive, but could not find the PCMCIA controller.
I went online and tried several pieces of software, alas, to no avail.
Hitachi (the laptop manufacturer) stopped supporting my particular machine about a year ago, so there is no info on their site.
I am stuck.
