This board as basically identical to the T500, and has very similar disassembly.
|
|
|
|
|
You must take it apart and flash the chip externally.
|
|
|
|
|
|
|
|
|
|
The chip is 4MiB NOR flash (SPI protocol) is SOIC8 form factory.
|
|
|
|
|
|
|
|
|
|
Refer to the following guide:\
|
|
|
|
|
[Externally rewrite 25xx NOR flash via SPI protocol](../install/spi.md)

Unlike other GM45+ICH9M thinkpads in libreboot, the R500 doesn't have an Intel
|
|
|
|
|
PHY (for Gigabit Ethernet). However, libreboot still includes an Intel flash
|
2021-05-18 12:21:48 +00:00
|
|
|
descriptor, but with just the descriptor and BIOS region. The `ich9gen` program
|
|
|
|
|
supports this fully.
|
|
|
|
|
|
|
|
|
|
Therefore, you do not have to worry about the MAC address. The onboard NIC for
|
|
|
|
|
ethernet is made by Broadcom (and works in linux-libre).
|
|
|
|
|
|
|
|
|
|
Refer to T500 disassembly guide. The R500 disassembly procedure is almost
|
|
|
|
|
identical.
