10 To port to other arches:
12 # cd /usr/share/genkernel
13 # cp -Rp x86 ${myarch}
14 # mkdir /usr/share/genkernel/pkg/${myarch}
16 Modify what is needed in the /usr/share/genkernel/${myarch}
17 directory, as well making a generic kernel-config.
19 IMPORTANT KERNEL NOTES:
20 - You MUST have /dev/pts turned on.
21 - If you want Bootsplash, you MUST have VESAFB enabled for 2.6,
22 other framebuffers won't work. You MUST also enable
23 "video mode selection support" and "Framebuffer Console support"
24 - From gentoo-dev-sources-2.6.8 and above, bootsplash has been replaced
25 with gensplash. Gensplash has the same kernel configuration requirements
26 as bootsplash, but works properly with any framebuffer device.
27 - To build a kernel with Genkernel you must have
28 "Block devices->Loopback device support"
29 "Block devices->RAM disk support"
30 - To boot genkernel properly, the kernel config must have
31 RAM disk support and Initial RAM disk support. You should
32 also set your "Default RAM disk size to 8192"
34 BOOTING A KERNEL WITH INITRD:
37 real_root= needs to point to your root partition
38 root= needs to point to the ramdisk (should stay at /dev/ram0)
39 init= needs to point to the linuxrc file to execute on the ramdisk
40 vga= should be the resolution you want your screen. 0x317 is
41 1024x768 - 16bpp and you'll get a pretty bootsplash if
