# Supermicro X9SAE and X9SAE-V

|
|

This page describes how to run coreboot on the Supermicro [X9SAE] and [X9SAE-V]
|
|
|

|
|
The flash IC is located between the PCH and the front panel connector,
|
|
(circled) sometimes it is socketed.
|
|
|
|
|
|
### How to flash
|
|
|
|
Unlike ordinary desktop boards, the BIOS version 2.00 of X9SAE-V does not
|
|
apply any write protection, so the main SPI flash can be accessed using
|
|
[flashrom], and the whole flash is writable.
|
|
|
|
Note: If you are going to modify the ME region via internal programming, you had
|
|
better disable ME functionalities as much as possible in the vendor firmware
|
|
first, otherwise ME may write something back and break the firmware you write.
|
|
|
|
The following command may be used to flash coreboot. (To do so, linux kernel
|
|
could be started with `iomem=relaxed` or unload the `lpc_ich` kernel module)
|
|
|
|
Now you can [flash internally](/flash_tutorial/int_flashrom.md). It is
|
|
recommended to flash only the `bios` region (use `--ifd -i bios -N` flashrom
|
|
arguments), in order to minimize the chances of messing something up in the
|
|
beginning.
|
|
|
|
The flash chip is a SOIC-8 SPI flash, and may be socketed, so it's also easy
|
|
to do in-system programming, or remove and flash externally if it is socketed.
|
|
|
|
## Difference between X9SAE and X9SAE-V
|
|
On X9SAE PCI-E slot 4 is absent. Lane 9~16 of PCI-E slot 6 on X9SAE are wired
|
|
to slot 4 on X9SAE-V. Unlike ASUS P8C WS, there is no dynamic switch on X9SAE-V,
|
|
so on X9SAE-V slot 6 can work as x8 at most.
|
|
|
|
On X9SAE-V device pci 01.1 appears even if not defined in devicetree.cb, so it
|
|
seems that it shall not appear on X9SAE even if it is defined.
|
|
|
|
## Working (on my X9SAE-V)
|
|
- Intel Xeon E3-1225 V2 with 4 M391B1G73BH0-YK0 UDIMMs, ECC confirmed active
|
|
- PS/2 keyboard with SeaBIOS 1.14.0 and Debian GNU/Linux with kernel 5.10.46
|
|
- Use PS/2 keyboard and mouse simutaneously with a PS/2 Y-cable
|
|
- Both Onboard NIC
|
|
- S3 Suspend to RAM
|
|
- USB2 on rear and front panel connectors
|
|
- USB3
|
|
- Integrated SATA
|
|
- CPU Temp sensors (tested PSensor on GNU/Linux)
|
|
- LPC TPM on TPM-header (tested tpm-tools with TPM 1.2 Infineon SLB9635TT12)
|
|
- Native raminit
|
|
- Integrated graphics with libgfxinit
|
|
- Nvidia Quadro 600 in all PCIe-16x slots
|
|
- Compex WLM200NX (Qualcomm Atheros AR9220) in PCI slot
|
|
- Debug output from serial port
|
|
|
|
## Untested
|
|
|
|
- EHCI debugging
|
|
- S/PDIF audio
|
|
- PS/2 mouse
