Created attachment 133493 [details] dmesg during cd boot with Arch kernel 4.12.3 Hi, I have a Lenovo E420s Laptop with a hybrid ATI/Intel Card and the Radeon Ca= rd wasn't detected correctly for ages. Now I noticed that, since I changed my = Boot from BIOS to UEFI it is detected correctly at the boot from the Install/Res= cue CD but still not at the boot from my hard drive. I am running Arch Linux. The message "[drm:radeon_get_bios [radeon]] *ERROR* Unable to locate a= BIOS ROM" appears in the dmesg output during the hard drive boot but not du= ring the CD boot. Because of a suggestion on the Arch BBS (https://= bbs.archlinux.org/viewtopic.php?pid=3D1730357) I am trying to report this bug here. I hope this helps.

Can you identify what the differences are between those two ke= rnels?
I copied the 4.12.3 kernel from the cd to the hd an bootet it = from the hd. It occurs the same error as with the 4.12.6 kernel.

I fixed it a few minutes ago. It was GRUB related. I installed Syslinux and it worked. I assume it has to do with the BIOS option "enable the discrete card i= f the OS supports hybrid graphics". (The other option is "disable discrete= card" ...). Thank you anyway for your help. :)
