And we can't cache the ROM because of CAR?
yes.
I am not convinced that failing to find files has to be a performance critical path - While I generally agree it must not take several seconds, something's wrong with our logic if we fail to find files before we have RAM and Cache enabled.
I think we should eliminate all unnnecessary overhead. Scanning (e.g.) 2 Mbytes of memory for each failed lookup -- all the other BIOSes are going to point at us and make rude comments :-)
I really would like us to have a reasonable termination instead of searching all of memory. It can be anything -- make a file name called EOF. Carl-Daniel's design was nice because it was very flash-friendly, but I'm not picky.
