The clock chip is ICS 9LPRS485CGLF - Could be used for overclocking.
It uses Elixir n2tu1g16dg-ac, DDR2 800 Mhz.
It uses Winbond W83627DHG. Its GPIOs are connected this way:
GP20 - sideport voltage 1 = 1.82V 0 = 1.92V
GPO40 | GPO41 | GPIO23 GPU voltage - 000 - 1.45V step 0.05 -- 111 - 1.10V
GPO35 - loadline control (0 enabled)
GPO44 | GPO45 | GPO46 - DDR memory voltage

- Using 2 512 MB DIMMs I got 756 MB of usable RAM (as opposed to 881 with the vendor BIOS).
- With only 1 512 MB DIMM the system wouldn't boot.
- With my 4 DIMMS from 3 vendors (2x A, 1x B, 1x C) I get the following boot chances. These might be related to another issue and not to the port of this board.
- Sometimes the link seems slow. It doesn't happen every boot. If it happens, SeaBios needs a long time to load grub. Also, the devicenodes in /dev are not in the right order according to the ports on the board. There are also the following messages during boot:
ata2: link is slow to respond, please be patient (ready=0) ata2: COMRESET failed (errno=-16) ata2: link is slow to respond, please be patient (ready=0) ata2: COMRESET failed (errno=-16) ata2: link is slow to respond, please be patient (ready=0) ata2: COMRESET failed (errno=-16) ata2: limiting SATA link speed to 1.5 Gbps ata2: link is slow to respond, please be patient (ready=0) ata2: COMRESET failed (errno=-16)
- Apart from the slowness all 5 ports seemed to work.
- If the above error didn't occur all 5 ports seemed to work flawlessly.
- It seems this error only occurs for the first time after a BIOS switch. With the proposed patches (fix and cleanup from 10/08/16) even the vendor bios triggers a kernel panic upon first boot after coreboot was loaded. Something about IRQ issues.
- With the newest patch (at least) I get these messages on serial console during boot
drive detection not yet completed, waiting... 0x6=b0, 0x7=80 drive detection selected after 540 ms, retrying 0 ms Primary Slave device is rstatus = 23 0x6=a0, 0x7=80 drinot yet completed, waiting... 0x6=a0, 0x7=80 drive detection not yet completed, waiting... 0x6=a0, 0x7=80 [snip]
- In regard to the vendor BIOS the output numbers were switched. DVI-0 (vendor BIOS) was named HDMI-0 using coreboot.
- Both VGA and DVI output worked.
PCI-E graphics adapter
- Wouldn't work. With both plugged in and CONFIG_CONSOLE_VGA_ONBOARD_AT_FIRST not set there was no video output. I had the vgabios for the onboard adapter still inside the coreboot.rom however.
Keyboard in Grub
- The (USB) keyboard in Grub doesn't respond correctly. Every keypress triggers multiple actions.
- Linux 18.104.22.168 wouldn't boot. It would start, then the screens were going blank and the machine hung.
