mb/dell: Add Dell Optiplex 790
This port was generated using autoport.
The Optiplex 790 comes in four different sizes: MT, DT, SFF and USFF. The mainboard PCBs for MT and DT are identical, the only difference is that MT has an extra SATA port. The other PCBs are slightly different, but they are designed with intercompatibility in mind.
Therefore, the four mainboard configurations are:
- MT: 4 RAM slots, 4x SATA, PEG, PCIe x1, PCI, PCIe x16 - DT: 4 RAM slots, 3x SATA, PEG, PCIe x1, PCI, PCIe x16 - SFF: 4 RAM slots, 3x SATA, PEG, PCIe x16 - USFF: 2 RAM slots, 2x SATA, mPCIe
This port has been tested with: SFF (needs retest) , USFF
What works: - Booting Arch Linux with kernel 5.2.3-arch1-1-ARCH - PCIe (Hotplug on PCIe X1 only!) - Onboard graphics with libgfxinit (via VGA) - Hard drive activity LED - Onboard sound - Onboard Ethernet - SATA (hotplug) - IOMMU - Turning on and off (S5) - Suspend/resume (S3) - EHCI debug (rear side, bottom port on the block with ethernet)
What does not work: - SuperI/O (Chip is a SCH5544-NS) - Serial port - PS/2 - Fan control (fans run at full speed) - Front LEDs (signals code 234, corrupted or defective BIOS) [1]
- VBT is missing
Untested: - DisplayPort? - VGA BIOS?
Further notes: - Default IFD settings block reads/writes to some regions. This can be bypassed by plugging the SERVICE_MODE jumper. BIOS version A05 does not set any protected ranges, so internal flashing is possible (use a layout if the SERVICE_MODE jumper is not plugged). - The mainboard has two flash chips: SOIC16 8 MiB and SOIC8 2 MiB. They are recognized as one "Opaque flash chip" of 10 MiB in size.
