Okay, now I've run into another snag. Once I lseek to the offset (defined as
0x1ff00000000 (where pci stuff starts, as I was told by someone else) plus
0x00010000 (the ROM address of the controller card)), I get EBADF from
read(). According to everything I've been told in my efforts to get a dump
of this firmware, there SHOULD be 128k there for me to read, but I get EBADF
regardless of whether I use lseek() or pread(). Any hints?
