+# Intel DG43GT
+
+This page describes how to run coreboot on the [Intel DG43GT] desktop.
+
+## Flashing coreboot

+```eval_rst

+| Dual BIOS feature   | No         |
++---------------------+------------+
+| Internal flashing   | yes        |
++---------------------+------------+
+```
+
+### Internal programming
+
+The SPI flash can be accessed internally using [flashrom].
+Only the BIOS region can and needs to be written to.
+
+```bash
+     $ flashrom -p internal --ifd -i bios -w coreboot.rom --noverify-all
+```
+
+### External programming
+
+ISP (in circuit programming) seems to be impossible on this board, which
+is a property it shares with many boards featuring the ICH10 southbridge.
+**Recovering from a bad flash will require desoldering the flash!**
+Desoldering the SPI flash can easily be done with a hot air station.
+Apply some flux around the SPI flash, set the hot air station to 350-400°C
+and after heating the chip up for a minute it should be possible to remove it.
+
+Having removed the flash chip, you can reprogram it externally then resolder
+it using a soldering iron.
+Another option would be to hook up a SPI flash (socket) to the SPI header,
+for easier flash removing in the future (if you expect to be hacking on this
+board). To do this you first need to solder the SPI header to the board.
+
+**NOTE: This header cannot be used for ISP either.**
+
+**NOTE2: Don't forget to connect the WP# and HOLD# pin on the SPI flash to 3.3V.**
+
+The layout of the header is:
+
+```
+                  +---+---+
+           GND <- | x | x | -> SPI_CLK
+                  +---+---+
+          3VSB <- | x | x | -> SPI_MISO
+                  +---+---+
+                  |   | x | -> SPI_MOSI
+                  +---+---+
+        SPI_CS# <-| x | x | -> SPI_CS# (again)
+                  +---+---+
+```
