The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!

proprietary components status
- CPU Microcode (optional?)
- VGA option rom (optional): without it you will get no graphics during early boot, old kernel versions(like the one in trisquel 6) are able to initializes the intel graphic card. Note that the replacement doesn't work yet with seabios but works with grub(as a payload) or libpayload based payloads.
- EC(Embedded Controller) => you do not have to touch it(just leave it where it is)
Non-free components replacements
Replace the non-free VGA option rom by making native graphics init work.submited for review.
- Create a Native graphics<->VGA option rom.
- Make backlight work without the non-free option rom.
- Add support for more batteries in ACPI.
- Make the wifi card and/or the laptop produce less heat.
- Finish and merge support for thinkpad_acpi linux kernel module
- Sometimes some dock USB port aren't initialized => fix that
- Fix that warning:
[ 14.566817] ACPI Warning: 0x00000400-0x0000041f SystemIO conflicts with Region \_SB_.PCI0.SBUS.SMBI 1 (20130117/utaddress-251)
By using that advise:
<phcoder> GNUtoo-x60: in this case it looks like same range is declared twice in DSDT/SSDT
Without the VGA optiorn rom nvramtool says:
# ./nvramtool -a nvramtool: coreboot table not found. coreboot does not appear to be installed on this system. Scanning for the table produced the following results: 0 valid signatures were found with bad header checksums. 0 valid headers were found with bad table checksums.
Fortunately there is a workarround:
# ./nvramtool -y ../../src/mainboard/lenovo/x60/cmos.layout -a boot_option = Fallback last_boot = Fallback baud_rate = 115200 debug_level = Emergency hyper_threading = Enable nmi = Disable # Bad value -> boot_devices boot_default = 0x40 cmos_defaults_loaded = Yes lpt = Disable volume = 0xc tft_brightness = 0xf first_battery = Primary bluetooth = Disable
To get cbmem console working you need the non-free i915 option rom or native graphics(doesn't work yet, don't use). Even with a dummy VGA option rom it fails:
[root@X60 cbmem]# ./cbmem -c -VVV Looking for coreboot table at 0 Mapping 1MB of physical memory at 0x0. Unmapping 1MB of virtual memory at 0xb7463000. Looking for coreboot table at f0000 Mapping 1MB of physical memory at 0xf0000. Failed to mmap /dev/mem: Operation not permitted [root@X60 cbmem]# dmesg -c [26300.943482] Program cbmem tried to access /dev/mem between f0000->1f0000.
Using fmem doesn't work either:
[root@X60 cbmem]# ./cbmem -c -VVV Looking for coreboot table at 0 Mapping 1MB of physical memory at 0x0. Unmapping 1MB of virtual memory at 0xb74ae000. Looking for coreboot table at f0000 Mapping 1MB of physical memory at 0xf0000. Unmapping 1MB of virtual memory at 0xb74ae000. No console found in coreboot table. [root@X60 cbmem]# dmesg -c [26404.984342] fmem init_module 449: init [26404.984349] fmem find_symbols 439: set guess_page_is_ram: c10440b0
Go in console:
[*] Send console output to a CBMEM buffer (0x10000) Room allocated for console output in CBMEM (0xc00) Room allocated for console output in Cache as RAM
The following commit might be interesting to cherry-pick:
git fetch http://review.coreboot.org/coreboot refs/changes/03/3403/3 && git cherry-pick FETCH_HEAD
Dmidecode from the BIOS says:
BIOS Information Vendor: LENOVO Version: 7BETC7WW (2.08 )
So in make menuconfig go in
General setup --->
And modify Local version string accordinly
(7BETC7WW (2.08 )) Local version string
Then locate the following in dmidecode:
System Information Manufacturer: LENOVO Product Name: 1707Y8W Version: ThinkPad X60 Serial Number: L3BY949
(L3BY949) Serial number (ThinkPad X60) Version number (LENOVO) BIOS table vendor string (ThinkPad X60 / X60s) BIOS table part number string
Then configure and build coreboot as usual
To modprobe the module use that:
modprobe thinkpad_acpi force_load=1 debug=0xffff fan_control=1 experimental=1
The module should now load automatically...
