### How to flash
|
||
|
|
|
||
|
|
The main SPI flash cannot be written because the vendor firmware disables BIOSWE
|
||
|
|
and enables BLE/SMM_BWP flags in BIOS_CNTL for their latest BIOSes. An external
|
||
|
|
programmer is required. You must flash standalone, flashing in-circuit doesn't
|
||
|
|
work. The flash chip is socketed, so it's easy to remove and reflash.
|
||
|
|
|
||
|
|
## Working
|
||

|
||
|
|
- Integrated graphics with libgfxinit (VGA/DVI-D/HDMI tested and working)
|
||
|
|

|
||
|
|
|
||
|
|
## Untested
