### Get the ROM image
**[Download](../../download.md) from release**
**[Build](../build/) from source**
./mk -b coreboot asus_kgpe_d16_2mb
*Replacable and upgradeble flash chip sizes possible, if done, adjust the 2mb (max 16mb) to it*
### Internal/Software Flashing
**Default RBoot firmwares [updatable](../install/simplified-sw-flashing.md).**
### External/Hardware Flashing
The default ASUS firmware write-protects the flash, so you have to remove the
chip and re-flash it using external hardware.
It has a 25XX NOR flash (SPI protocol) in a P-DIP 8 socket, which looks like
this:
The default chip is a 2MiB one, but we recommend upgrading it to a 16MiB chip.
The basic [guide](../install/simplified-hw-flashing.md) is not enough for this board,
read the [full guide](../install/spi.md) as well.
### Device Unique Properties
#### Physically backup up vendor firmware
Dumping the factory bios, then hot-swapping the flash to keep to flash RBoot on it, and keep the original too.
#### Form factor
- SSI EEB 3.61 (12"x13")
#### IPMI iKVM module add-on
IPMI iKVM module (optional add-on card) uses proprietary firmware.
Since it's for remote out-of-band management,
it's theoretically a backdoor similar to the [Intel Management Engine](../../faq.md#intelme).
Fortunately, unlike the ME,
this firmware is unsigned which means that a free replacement is theoretically possible.
For now, the RBoot project recommends not installing the module.
[This project](https://github.com/facebook/openbmc) might be interesting to derive from,
for those who want to work on a free replacement.
In practice, out-of-band management isn't very useful anyway
(or at the very least, it's not a major inconvenience to not have it).
#### Flash chips
The flash is hot-swappable in a 25xx NOR, P-DIP8 form factor.
*DO NOT hot-swap the chip with your bare hands. Use a P-DIP 8 chip
extractor. These can be found online. See
*
Ideally, you should not hot-swap. Only remove the IC when the system is
powered down and disconnected from mains.
#### Graphics
Text-mode works with ast2050. See [\#graphics](#graphics)
