You can use the dumpsetup.py script to construct a description of all EFI forms in the setup PE. That's the straightforward part done - now you'll have to start using some initiative. Examining and modifying the setup program At least for the 311, the python script identifies this as having a GUID (globally unique identifier) of fe3542fe-c1d3-4ef8-7c65-8048606ff670. The BIOS setup utility is a portable executable named 'SetupUtility'. You should have a large number of files with the extensions. You have now pulled the BIOS apart into component modules. Dump the file system and retrieve the setup program In the case of the F15 BIOS on the 311 this is named fv-00000010.bin. Before the next step, you need to choose the main volume (probably the biggest, with lowest file number). You now have a number of files named fv-?.bin. scanlzma 0 3651F150.bin Dump the firmware volumes Use scanlzma to decompress the image, substituting 3651F150.fd with your fd file and 3651F150.bin with whatever you want the decompressed output to be called. If you haven't already compiled scanlzma, do so now: Switch over to Linux, where you can easily strip the header and decompress the image. The ROM image comprises an uncompressed header, followed by an LZMA compressed image. If multiple images exist, check the size - they will apply to different size EEPROMs. Open with 7-zip and extract the ROM image you wish to use (e.g. In the case of the HP 311 this contains another self-extracting executable, which in turn contains the flash utility and ROM images.

The BIOS update is normally provided as a self-extracting Windows executable. Get these source files from Marcan's site, and make sure you have python, lzma and gcc installed on Linux. There are several ways of doing this, and the following is just how I did it - I use both Linux and Windows. At present, these notes mainly cover unpacking the BIOS into it's component parts.
