OmniBook 300, 425 and 430 US ROM Image?

[hitaka2006]

I am collecting OmniBooks, and wondering if someone can share ROM image with me. I've found 425 ROM image on the internet, while it was UK version. I'm looking for US ROM image for OB 300, 425, and 430.

FYI, I could write image on linear flash card by using OmniDrive USB2 LF. However, I'm failing to read image from OB ROM cards. If someone can tell me how I can read using the drive, I'll be able to share French 425 ROM and Spanish 430 ROM images.
