Hardware details

Clock Chip

The clock chip is ICS 9LPRS485CGLF - Could be used for overclocking.

Sideport memory

It uses Elixir n2tu1g16dg-ac, DDR2 800 Mhz.

SuperIO

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

Suspend LED is the power LED - register 0f3 in SIO. Low = on

PCIe x16

Reset signal is through GPIO - GPM8,GPM9, 0 asserts reset, 1 de-asserts reset.

Known Issues

SATA

External and SATA port 4 is not detected. This is due to bug in Coreboot code with regards of Combined mode handling.

RAM

Ruik tests

  • use 2x 512MB CAS 2.5 DDR400
  • blue slots populated = dualchannel mode (works)
  • all slots populated (with additional RAM) - strange UMA artefacts
  • only channel0 populated (DDR1 and DDR3 slot, DDR1 is closest to CPU) - strange UMA artefacts
  • single memory stick in DDR1 slot - works

Lennart tests

  • blue slots populated - works
  • all slots populated -- doesn't boot
    • hangs on "Clearing initial memory region:"
  • only channel0 populated - doesn't boot
    • hangs on "Clearing initial memory region:"
  • single DIMM in DDR1 - works.

Onboard VGA

  • 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

  • Should be now fixed - r6384


Keyboard in Grub

  • The (USB) keyboard in Grub doesn't respond correctly. Every keypress triggers multiple actions.

Kernel

  • Linux 2.6.35.2 wouldn't boot. It would start, then the screens were going blank and the machine hung.
