We've seen quite a bit of MS-Windows geekery lately, so now let's have
some UN*X geekery. :)

Assuming I patched the binary correctly as indicated by your diff, there
is indeed a match:

firmware/drives/old/8050/d/8250romfdc-fc00

That file includes the start address, $00, $FC.  If you have recent GNU
cmp (or BSD cmp, I think), you should be able to skip the two
start-address bytes when comparing to the (raw) dump, like so:

$ cmp -l -i 2:0 8250romfdc-fc00 fdc-dump.bin
