Angel Pons submitted this change.
mainboard/asus/p8x7x-series: Add new variant P8Z77-M
Constructed out of a mix of autoport results, p8z77-m_pro, and
tool dumps.
Working:
- Core i7-3770K CPU
- SeaBIOS 1.13.0 boot to Linux 5.4.24 and Windows 10 1903
(all further tests are under these versions)
- USB2 / USB3
- SATA
- Gigabit ethernet
- CPU temp sensors (memtest86+ 5.0.1)
- Hardware monitoring under Linux
- Native and MRC raminit
- PCIe GPU in both "PCIEX16" slots (16x/4x, nVidia Quadro 600)
- Integrated graphics with Intel OpROM and libgfxinit (all ports)
- Serial port
- Windows with libgfxinit framebuffer
- 2ch sound playback, Linux and Windows
Not working:
- PS/2 mouse
- 6ch analog audio out
- PCI POST card in PCI slot
Untested:
- PS/2 keyboard
- Internal USB3 ports
- Digital audio out
