Several variants of the H8QGi motherboard are highly supported by [[coreboot-15h]], namely the H8QGi+-F and H8QG6+-F. The H8QGi motherboards have 4 [[G34]] sockets, each with 8 DIMM slots; supporting a maximum configuration of 64 cores and 1 TB of RAM. LRDIMM modules may bring the maximum memory up to 2 TB, but LRDIMM support has not been tested.
== Board Variants ==
=== H8QGi+-F ===
The H8QGi+-F is the base model of the H8QGi series, all other variants have additional features. Compatibility of the onboard BMC with coreboot has not been tested; it can be disabled via the "JPB1" motherboard jumper.

=== H8QG6+-F ===
The H8QG6+-F has an onboard SAS controller; it can be flashed to IT mode.

=== H8QGi+-LN4F ===
The H8QGi+-LN4F has four onboard LAN ports. It is likely compatible with the coreboot image for H8QGi+-F, but this has not been tested.

=== H8QG7+-LN4F ===
The H8QG7+-LN4F has an onboard SAS controller and four onboard LAN ports. It is likely compatible with the coreboot image for H8QG6+-F, but this has not been tested.

=== H8QGi-F ===
The H8QGi-F is a H8QGi+-F with a secondary northbridge and additional PCIe lanes. The coreboot image for the H8QGi+-F can be used, but the secondary northbridge and associated PCIe lanes will be offline.

=== H8QG6-F ===
The H8QG6-F is a H8QG6+-F with a secondary northbridge and additional PCIe lanes. The coreboot image for the H8QG6+-F can be used, but the secondary northbridge and associated PCIe lanes will be offline.

=== H8QGi-LN4F ===
The H8QGi-LN4F is a H8QGi+-LN4F with a secondary northbridge and additional PCIe lanes. It is likely compatible with the coreboot image for H8QGi+-F, but this has not been tested; the secondary northbridge and associated PCIe lanes will be offline.

=== H8QG7-LN4F ===
The H8QG7-LN4F is a H8QG7+-LN4F with a secondary northbridge and additional PCIe lanes. It is likely compatible with the coreboot image for H8QG6+-F, but this has not been tested; the secondary northbridge and associated PCIe lanes will be offline.

== Missing Features ==
* Support for the secondary SR5670 has not been implemented (PCIe slot 2 is offline).
* Support for the SR5690/SR5670 IOMMU has not been implemented.

== Flashing Firmware ==

To switch from the stock firmware to coreboot, [[External Flashing | external flashing]] is required.

=== Flash Chip Location ===
[[File:H8QGi Flashchip Location.png|frameless|300x300px]]

The flash chip is located below the circular CMOS battery slot.

=== Flash Chip Orientation ===
[[File:H8QGi Flashchip Orientation.png|frameless|300x300px]]

The circle marking the location of pin 1 is highlighted red in the above image. The circle is a subtle indentation on the chip that can be seen with the aid of a flashlight..
