[OB] Installing a CF in an Omnibook 425 or 430

[Michel Bel]

Yes, it would all work.

Note that you would have a 'plain vanilla' dos system, but NOT a plain 
vanilla notebook:
the PCMCIA slot is pre-standard and does not support that much hardware.

Also, stick to Sandisk CF/PCMCIA cards, many others are not recognized by 
the 425/430 bootloaders/bios.
