POSIX-UEFI Utilities
|
||
|
|
====================
|
||
|
|
|
||
|
|
These are small portable commands to help you with the UEFI toolchain (libc only, no EFI headers needed). They convert the .efi
|
||
|
|
output that you've compiled with POSIX-UEFI into different file formats required by the UEFI firmware.
|
||
|
|
|
||
|
|
* __efirom__ - creates a PCI Option ROM image
|
||
|
|
```
|
||
|
|

|
||
|
|
|
||
|
|
./efirom [--vendor=VVVV] [--device=DDDD] infile outfile
|
||
|
|
```
|
||
|
|
|
||
|
|
* __efiffs__ - creates a DXE UEFI driver image (see [this wiki](https://github.com/pbatard/efifs/wiki/Adding-a-driver-to-a-UEFI-firmware#adding-the-module-to-the-firmware) on how to add it to a firmware).

|
||
|
|
|
||
|
|
./efiffs [-g <guid>] [-n <name>] [-v <ver>] [-t <type>] [-p <type>] infile [outfile]
|
||
|
|
|
||
|
|
-g <guid> specify the GUID (defaults to random)
|
||
|
|
-n <name> specify the driver's name (eg 'FAT')
|
||
|
|
-v <ver> specify the driver's version (eg '1.0')
|
||
|
|
-t <type> specify the ffs type (defaults to 7, EFI_FV_FILETYPE_DRIVER)
|
||
|
|
-p <type> specify the pe section type (defaults to 16, EFI_SECTION_PE32)
|
||
|
|
infile input .efi file
|
||
|
|
outfile output file name (default generated from infile)
|
||
|
|
```
|
||
|
|
|
||
|
|
* __efidsk__ - creates a bootable disk image with EFI System Partition from the contents of a directory. Copy the POSIX-UEFI
|
||
|
|
compiled file under the given directory as `EFI/BOOT/BOOTX64.EFI` to get it automatically booted.
|
||
|
|
```
|
||
|
|

|
||
|
|
|
||
|
|
./efidsk [-p|-c] [-s <size>] indir outfile
|
||
|
|
|
||
|
|
-p save only the partition image without GPT
|
||
|
|
-c save EFI CDROM (ISO9660 El Torito no emulation boot catalog)
|
||
|
|
-s <size> set the size of partition in megabytes (defaults to 33M)
|
||
|
|
indir use the contents of this directory
|
||
|
|
outfile output image file name
|
||
|
|
```
