Hey all,
im working at the on the i810, trying to fix the onboard-vga to work.
removing the commented code of the vga-related stuff resulted with the pci device to be displayed in the pci list on coreboot, but in a disabled state, and (as promised...) with the boot not executing the payload. complete log can be shown here : http://pastebin.com/m20e821eb
a few rough patches to my target and i82810/raminit.c and now the device is shown as enabled and i even get the information about the VGA allocating resources :
Allocating VGA resource PCI: 00:01.0 Setting PCI_BRIDGE_CTL_VGA for bridge PCI_DOMAIN: 0000 Setting PCI_BRIDGE_CTL_VGA for bridge Root Device
but the payload still wont execute (it is seems to be loaded though) and ofcourse, no VGA output, only serial, with a dead boot hanging... complete log can be shown here : http://pastebin.com/m248a41ea
i'd appreciate any clues/assistance in the matter.
Regards, Elia Yehuda.

I had this problem on the i830. You need to allocate vga memory for the onboard vga (northbridge.c if I remember correctly). The vga memory should be allocated to the TOM. So your total system memory actually equals phisical memory - vga memory. It should be close to the i830, take a look at that and compare it to the i810 datasheet. Hope that helps.
