Problem with GPT Bios Partition

[Denny Bortfeldt]

Hey Kerim,

no not really - my disk_config could be/is wrong.
The following schema need to be created by FAI disk_config:

GPT /dev/sda1 2048 6143 2M BIOS boot partition /dev/sda2 6144 16783359 8G
Linux swap /dev/sda3 16783360 17831935 512M Microsoft basic data /boot
/dev/sda4 17831936 49289215 15G Microsoft basic data / /dev/sda5 49289216
7812456414 3.6T Linux LVM

But here's the problem: I don't know how.
The /dev/sda1 partition don't have got a mount point and is a type "4" in
fdisk/gdisk - so I don't know what I need to write in my disk_config so
that FAI will use "type 4" in partition layout.
/dev/sda2, /dev/sda3 and /dev/sda4 is clear - everything is "primary" and
swap or ext4.


So what do I need to enter in my disk_config that the result will look like:

/dev/sda1 2048 6143 2M BIOS boot partition

Thanks in advance :)

Best regards,
Denny
