* [util] Add support for EFI ROM imagesPetr Borsodi2019-01-211-0/+13
| | | | | | | The Option::ROM module recognizes and checks EFI header of image. The disrom.pl utility dumps this header if is present. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [util] Improve processing of ROM images in Option::ROMPetr Borsodi2019-01-211-5/+7
| | | | | | | | | | The Option::ROM module now compares the Code Type in the PCIR header to 0x00 (PC-AT) in order to check the presence of other header types (PnP, UNDI, iPXE, etc). The validity of these headers are checked not only by offset, but by range and signature checks also. The image checksum and initial size also depends on Code Type.

* [romprefix] Report a pessimistic runtime size estimateMichael Brown2012-07-231-0/+11
| | | | | | | | | | | | | | | | PCI3.0 allows us to report a "runtime size" which can be smaller than the actual ROM size. On systems that support PMM our runtime size will be small (~2.5kB), which helps to conserve the limited option ROM space. However, there is no guarantee that the PMM allocation will succeed, and so we need to report the worst-case runtime size in the PCI header. Move the "shrunk ROM size" field from the PCI header to a new "iPXE ROM header", allowing it to be accessed by ROM-manipulation utilities such as disrom.pl. Reported-by: Anton D.

* [util] Allow Option::ROM to understand and modify initialisation entry pointMichael Brown2008-08-151-0/+1
| | | | | | | | | | | | | | Add support for manipulating the jump instruction that forms the option ROM initialisation entry point, so that mergerom.pl can treat it just like other entry points. Add support for merging the initialisation entry point (and IBM BOFM table) to mergerom.pl; this is another slightly icky but unfortunately necessary GPL vs. NDA workaround. When mergerom.pl replaces an entry point in the original ROM, it now fills in the corresponding entry point in the merged ROM with the original value; this allows (for example) a merged initialisation entry point to do some processing and then jump back to the original entry point.
* [util] Add Option::ROM library and rewrite disrom.pl to use it.Michael Brown2008-07-311-100/+61Star
| | | | | The Option::ROM module provides an easy way to read and edit fields within option ROM headers.
