1# Lenovo Thinkpad R60 2 3Untested on boards with external Radeon graphics adapter. If you have such 4board, proceed at your own risk and document if it does work. 5 6## Flashing instructions 7 8### External flashing 9 10The flash IC is located at the bottom center of the mainboard. Access to 11the flash chip is blocked by the magnesium frame, so you need to disassemble 12the entire laptop and remove the mainboard. The flash chip is referenced as U49 in 13the schematics and in the boardview. 14 15 16 17To disassemble the laptop, follow the [Hardware Maintenance Manual](https://thinkpads.com/support/hmm/hmm_pdf/42x3749_02.pdf). 18 19### Internal flashing on Vendor BIOS 20 21This [method](https://gist.github.com/ArthurHeymans/c5ef494ada01af372735f237f6c6adbe) describes a way to install coreboot with vendor firmware still 22installed on the Lenovo Thinkpad X60. It is reported to also work in Thinkpad 23R60, with the only difference being the board target you build coreboot for. 24 25### Flashing on coreboot 26 27Default configuration of coreboot doesn't feature any flash restrictions 28like the vendor firmware, therefore flashrom is able to flash any rom without problems. 29 30## Things tested and working in Linux 5.3: 31 32- Intel WiFi card 33- Suspend and resume 34- Native graphics initialization. Both legacy VGA and linear framebuffer work 35- GRUB2 2.04 and SeaBIOS 1.12.1 payloads 36- Reflashing with flashrom (use flashrom-git as of 17.09.2019) 37- 2G+1G memory configuration working 38- 2504 dock USB ports if not hotplugged 39 40## Things tested and not working: 41 42- 2504 dock hotplugging 43- Black bar at the left side of the screen. Doesn't appear in Linux. See picture at top 44- Sometimes it takes several second to run coreboot. Just wait for it 45
