AFAIK, Book8088 still uses a customized https://github.com/skiselev/8088_bios BIOS build which does not support USB boot. I was unable to make it work in a few feeble, naive attempts. I may give it a more concerted try if I have some time later. Not a big concern when I can create working CF cards on another machine. IIRC, the Book8088's CF loads CH375S.SYS from DOS and attempts to mount a USB drive if a compatibly formatted drive is present.

I haven't attempted to update the BIOS either. I think I need to buy another 27C EEPROM chip for such attempts.
