Alright, I've got most of that stuff done, and the device is there. It just
reboots when I mount the bbram. :-) Got some work to do.
I want to use a file system to provide the abstraction layer so that I can
go to a hard drive if needed. Makes my life easier too, especially on
testing. My previous product had a 128KB BBRAM that was mapped to a DOS
floppy drive by the bios and formatted with FAT12, and that worked well.
Does the minix fs have a small overhead like FAT12? Could I use FAT12 if I
was willing to stick with 8.3? (Which wouldn't be a bad idea anyway, for
other reasons in my project).
Alright, one more question: What should the erasesize be for BBRAM?
Obviously I'm not worried about wear, so should it be zero or one or
