The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
Known Bad Configurations
These configurations should have been mentioned on HCL if they work in some situations.
|Mainboard PCB revision
|Fails under proprietary BIOS
|Known requirements to trigger bug
|Internal development version of coreboot
|Two DIMMs on one channel (i.e. a DIMM in at least one black slot)
|Severe memory corruption; coreboot goes into a reboot loop and the proprietary BIOS hangs on starting its PXE ROM(s). Leaving all black slots empty restores normal operation.
|Micron / HP
|MT36JSF2G72PZ-1G6E1LG (HP: 672612-081)
|More than 2 DIMMs per CPU
|Cannot boot (works fine with proprietary BIOS).
|Two DIMMs on one channel (i.e. a DIMM in at least one black slot).
|Crashes / Reboots (always boots).
On a side note: without proper cooling these gets really warm with Libreboot, unlike proprietary BIOS. However, the heat is not the problem but might be a symptom. (works fine with proprietary BIOS).
|Internal development version of coreboot (2017)
|One DIMMs on one channel (i.e. the DIMM is in the topmost one orange slot, A2)
|coreboot cannot send MCT request and goes into a reboot loop; the proprietary BIOS also enters a (quite fast) reboot loop before the VGA port can be initialized. These modules do not work at all with either coreboot or the proprietary BIOS regardless of slot location!
Both Micron DIMMs tested fails at >64GB with two CPUs, coincident?
