+# ASUS P8C WS
+
+This page describes how to run coreboot on the [ASUS P8H77-V].
+
+## Flashing coreboot
+
+```eval_rst
++---------------------+----------------+
+| Type | Value |
++=====================+================+
+| Socketed flash | yes |
++---------------------+----------------+
+| Model | W25Q64FVA1Q |
++---------------------+----------------+
+| Size | 8 MiB |
++---------------------+----------------+
+| Package | DIP-8 |
++---------------------+----------------+
+| Write protection | no |
++---------------------+----------------+
+| Dual BIOS feature | no |
++---------------------+----------------+
+| Internal flashing | yes |
++---------------------+----------------+
+```
+
+The flash IC is located beside the SATA ports (circled):
+![](p8c_ws.jpg)
+
+### How to flash
+
+Unlike ordinary desktop boards, the BIOS version 3202 of ASUS P8C WS does not
+apply any write protection, so the main SPI flash can be accessed using
+[flashrom], and the whole flash is writable.
+
+The following command may be used to flash coreboot. (To do so, linux kernel
+should be started with `iomem=relaxed`)
+
+```
+# flashrom -p internal -w coreboot.rom
+```
+
+The flash chip is a socketed DIP-8 SPI flash, so it's also easy to remove and
+flash externally.
+
+## Working
+- 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 5.10.40
+- 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 (both analog and digital output from DVI-I)
+- Nvidia Quadro 600 in all PCIe-16x slots
+- Compex WLM200NX (Qualcomm Atheros AR9220) in PCI slot
+- Onboard IEEE1394 controller under PCI bus
+- Debug output from serial port
+
+## Untested
+
+- EHCI debugging
+- S/PDIF audio
+- PS/2 mouse
+- LPT port
