Compatibility (without blobs)

- -

- Usual limitations apply for native graphics initialization - (no VBT and/or INT10H and only GRUB works so no BIOS, so no DOS/Windows support - - who cares? There is no system but GNU, and Linux is one of it's kernels). -

- -

- When connecting the AC adapter while system is powered off, system will then power on. - This probably happens in coreboot aswell (with or without blobs). - It's a minor annoyance, but it should be fixed (if it's not already fixed by now). -

- -

- This method of disabling the ME leaves the flash descriptor and gbe in place (non-functional data, fully documented) - and disables the ME using soft straps. This means that the gigabit ethernet will still work (putting the machine in - non-descriptor mode would wipe it out). -

Hardware virtualization (vt-x)

-

- The R400, when run without CPU microcode updates in coreboot, currently kernel panics - if running QEMU with vt-x enabled on 2 cores for the guest. With a single core enabled - for the guest, the guest panics (but the host is fine). Working around this in QEMU - might be possible; if not, software virtualization should work fine (it's just slower). -

-

- The following errata datasheet from Intel might help with investigation: - http://download.intel.com/design/mobile/specupdt/320121.pdf -

+ Thi R400 is almost identical to the X200, code-wise. See x200.html. +

+ TODO: put hardware register logs here like on the X200 and T400 page. +
