I figure that's a DVH "Disk Volume Header" as used on SGI machines. > mipsel > ====== > bytes 000-008 : 0-padding > 008-011 : magic header > 012-015 : boot mode > 016-019 : load address > 020-023 : exec address > 024-027 : boot file length > 028-031 : boot file location Looks like an Ultrix boot record for a DECstation. That's a list of boot file extents and their locations. For an ISO we can assume contiguous files, so it makes no difference in that case. > (otherwise blank - may contain other boot files, but we don't use it) There's only a single boot file. As a sidenote, there are other mips/mipsel system architectures with different firmware and disk layout conventions. This makes even building a CD which boots on all mips systems tricky.
