7020/9020 MT each have the same motherboard. Flash the 9020 ROM from Libreboot
on your 7020, and it will work.
Ditto 7020/9020 SFF, it's the same motherboard. However, Libreboot provides
separate targets for MT and SFF.
Build ROM image from source
---------------------------
For the MT variant (7020 MT and 9020 SFF):
./build roms dell9020mt_12mb
For the SFF variant (7020 MT and 7020 SFF):
./build roms dell9020sff_12mb
It is important that you choose the right one. The MT variant is the full
MTX tower.
Installation
============
Insert binary files
-------------------
If you're using a release ROM, please ensure that you've inserted extra firmware
required refer to the [guide](../install/ivy_has_common.md) for that. (failure
to adhere to this advice will result in a bricked machine)
Libreboot's build system automatically downloads and processes these files if
you build Libreboot from source, but the same logic that it uses must be re-run
if you're using a release image.
Set MAC address
---------------
This platform uses an Intel Flash Descriptor, and defines an Intel GbE NVM
region. As such, release/build ROMs will contain the same MAC address. To
change the MAC address, please read [nvmutil documentation](../install/nvmutil.md).
Flash a ROM image (software)
-----------------
If you're already running Libreboot, and you don't have flash protection
turned on, [internal flashing](../install/) is possible.
Flash a ROM image (hardware)
-----------------
**REMOVE all power sources and connectors from the machine, before doing this.
This is to prevent short circuiting and power surges while flashing.**
For general information, please refer to [25xx NOR flash
instructions](../install/spi.md) - that page refers to use of socketed flash.
This machine is somewhat cumbersome to flash, because it has a SOIC-16 flash
for the first 8MB part, and 4MB SOIC8. You can split up your 12MB ROM image
like so:
dd if=libreboot.rom of=4mb.rom bs=1M skip=8
dd if=libreboot.rom of=8mb.rom bs=1M count=8
The side cover comes off easily, and you can find the flash ICs next to the RAM.
Here's the SOIC8 ICs being flashed:
