I just had an idea which I’m not sure if it’d make sense to ask as a question here.
We know there are flash-to-IDE adapters, but has anyone ever made ‘flashcarts’ for PC compatibles? Something that connects to the ISA or PCI bus and presents flash storage not as an IDE drive, but mapped into the address space, like for example an expansion ROM.
This would have been useful for working around BIOS bugs and limitations. Like, one could write an expansion ROM that supports large disks, or booting from CD-ROM or USB, and then put it on such a ‘flashcart’ instead of writing it to the hard disk.

Sounds like there might be a few good questions around there, but “has anyone done this?” probably isn't great.
