[SOLVED] What is the difference between Partition identifier 83 and 8a

Hi All,

I know Partition identifier 83 means Linux native partition, 8a means
Linux Kernel Partition. But I just want know is it any performance improvement or anything else if we change the partition identifier from 83 to 8a. Because we can hold the kernel in 83 identifier partition also. In my system now I am holding static kernel on Partition 1 and the Identifier is 83.

Partition 8a was used for Air Boot bootloader

Partition ids come and go - I use the list fdisk knows about as my reference. No 0x8a.

Thank you all.

@keefaz: After read few articles, I understood if we use the Air-boot loader we can use the identifier as 0x8a. We can't use 0x8a partition with normal boot loader. Is my understanding correct?

Yes correct, I'm not even sure that recent air boot loaders still use this partition type (I noticed the vfat partition use on the home page)

Except for a few "container" types (0x05 "Extended", 0x85 "Linux extended", plus a few others) that hold additional levels of partitioning, Linux doesn't care about partition types. Most versions of fdisk will show the type as "unknown", but it will work just fine.
