GDT HELP

[beyondsociety]

I have added a offset to the beginning of my kernel code. I have added this whole offset to the GDTR base address and the far jump to protected mode.

Do I also have to add this offset to the loading in of the GDTR?

ex: lgdt [GDTR + offset]

No if you have added the [org old_org+offset] directive to the beginning of your code...

Whats the [org old_org + offset] drizzt?

[drizzt]

If your previous beginning address was for example 0x10000 and you add an offset 0x600, you write:

[org 0x10000+0x600]

In this case you do not have to specify GDTR + offset
