A logic analyzer is helpful. My investigations so far have led me to the fact that Qotom make the PC - The motherboard is made by somebody else. I don't know the motherboard is made by, but most likely a not widely know Chinese manufacturer selling en-mass to EOMs. I will need to physically remove the board and look for some identifying features. So far I have found a IT8718F LPC I/O chip, so the bios is in an SPI flash. I have an in-circuit SPI programmer, but there is no header on the motherboard to get at the flash chip - I may need to jury-rig some kind of connection to the flash chip (as soon as I locate it). Apart from the APU, South Bridge, IT8718F and SPI flash there are only a couple of 8-pin chips plus the Ethernet PHY and (I think) a HDMI driver. The APU and south bridge are, of course, covered by heatsinks. Can I assume a particular south-bridge chip (of course I can just install Linux and find out) > Depending on your experience and skill should expect to spend some > months on the project. I have a fair bit of experience (x86 port of U-Boot) so once I get access to the Flash, I should be able to hack it pretty quickly. Does the E350M1 port fully support booting and running Linux (including PCIe etc.)? Regards, Graeme -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
