The H8SGL motherboard is highly supported by [[coreboot-15h]].

== Open Source Firmware ==
Open source firmware for the H8SGL is provided by [[coreboot-15h]] utilizing AMD's open source AGESA and CIMx releases for platform initialization.

=== H8SGL ===
{{Excerpt|Coreboot-15h|[[H8SGL|SuperMicro H8SGL]]|hat=no}}
=== H8SGL-F ===
The H8SGL-F is identical to the H8SGL, but has an onboard BMC. It is compatible with the coreboot image for the H8SGL, but it is not known whether the onboard BMC will operate. The "JPB" motherboard jumper can be used to disable the onboard BMC, effectively turning the H8SGL-F into the H8SGL.
=== Missing Features ===
* Support 6100 series Opteron CPUs is untested.
* Support for the two onboard serial ports is untested.
* Support for the onboard BMC is untested.

=== Flashing ===
To switch from the stock firmware to coreboot, [[External Flashing | external flashing]] is required. The flash chip is located between PCI slots 2 and 3, near the SP5100.
