[Basic Question] Bootloader, IDT, GDT

Post by gonzalomelov »

Hi!

I was told to make a bootloader which, in the .asm file, needed to define a GDT with 3 TSS Descriptors,
a LDT for the Keyboard ISR with code and data segment, and the IDT with gate-descriptors.

The ISR we have to make are Keyboard and Timer.

My question is, do I have to put the firsts 31 exceptions entrys in the IDT or only 2 gate-descriptors,
one for each ISR?

Thanks and sorry for my english.
