Status

Nothing work yet, no output on serial.

Hardware

  • CPU: T7200
  • Northbridge: 945GM
  • Southbridge: ICH7-M
  • superio: SMSC LPC47N217
  • ec: SMSC LPC47N217
  • flash chip: M25PE80,1024 kB, soldered,SOIC-8

How to flash

  • disassemble the laptop
  • Put the power adapter in the laptop's power plug
  • power off the laptop
  • attach the pomona clip and flash(backup the BIOS before.)

how to unpack the BIOS

See http://paste.flashrom.org/view.php?id=1523

Ec Issue

The ec firmware(4000_KBC.bin) probably has to be in the image at the same fixed position than the BIOS.

Patch (not working)

The nc6320 is very similar to the Roda rk886ex, with only the superio that is different.
