Both ROMs can be reprogrammed in the future using an EPROM programmer. The UV-erasable M27C512 would require a UV lamp to erase the previous content, while the W27C512 Flash ROM can be electronically erased in the programmer

8088 compatible version supports both Intel 8088/80C88 and NEC V20 processors

Why did I make it?

The 8088 BIOS is an open source BIOS for 8088 based computers. I've been developing it since 2010, primarily to support my Xi 8088 and Micro 8088 projects. This BIOS is also used in the NuXT Turbo XT project.

Book8088 system that appeared early 2023, uses 8088 BIOS in violation of GNU Public License. In particular, the license and the copyright have been removed, also the distribution of the source code is uncertain. So far the manufacturer of Book8088 failed to comply with the terms of GNU license, citing non-sense excuses about not being able to sell systems that have software they don't own the copyright to (somehow everyone else does sell Windows and Linux systems, although they don't own the copyright).

By popular demand from the community I added official support for Book8088 to the 8080 BIOS. And now I offer preprogrammed ROMs with the BIOS for the folks that are unable to program the EPROMs themselves.
