First thing, if you think you take the hardrive out, use an adapater, and install win 95 on it, it will not work on the laptop, you'll get blue screens of death every time you boot.
The best thing to do is to boot from the cd if possible. Are there any options in the bios to boot from cd? or boot from pcmcia device? I don't have much experience with laptops so I'm just guessing on possible options you may have.
If you can't do that, then booting from a win 95 or win 98 startup disk is probably your best option. You can get images of the disks here:
http://www.bootdisk.com/ which you put onto a floppy and boot from the floppy. Theres a lot of information on installing onto older machines on that site so check it out and see if you can find something to help you. If not, let us know and maybe someone else can give a better suggestion.
