+# ITX-Llama BIOS
+
+This repo contains the tools necessary to build the [ITX-Llama](https://github.com/eivindbohler/itxllama) BIOS (Coreboot/SeaBIOS).  
+Based on the 86Duino project from https://github.com/roboard/build-coreboot  
+
+For help or feedback, try the [ITX-Llama thread on Vogons](https://www.vogons.org/viewtopic.php?t=93480)!
+
+Tested on:
+* Ubuntu 16.04 i386
+
+Other operating systems and architectures are likely simple to get working as well, but your mileage may vary.  
+The easiest option is probably to spin up a virtual machine of some kind, and install Ubuntu 16.04 i386 on that.
+
+### Prerequisites
+#### Ubuntu
+Install tools:
+```
+$ sudo apt install git build-essential m4 bison flex python texinfo gnat
+```
+### Build the cross compiler
+```
+$ ./build-xgcc.sh
+```
+
+### Build the ROM file
+```
+$ make
+```
+
+If building is successful, the 2 MB output ROM file will be in the `out/` directory.
+Another file is also made - `out/xxx-padded.rom` - padded with `0xFF` to fit 8 MB, for flashing directly to the SPI ROM using a hardware programmer. The Coreboot/SeaBIOS ROM will be located at the end of this 8 MB file.
