Hi,

I am studying the PS2SDK code and to find what I can help. I noticed in kernel.S ,some function are provided as an interface to syscall, my question is: who will provide the syscall exception vector, the ps2link or PS2 internal BIOS?

very curious, thanks in advance.

The PS2 kernel, of course.

where is the PS2 Kernel?

Seems this board is very quiet...

The kernel is in the PS2's ROM. There's a bunch of routines there to handle
threads and semaphores and other stuff.

The PS2 kernel pretty much is the BIOS, all it does in implement the functionality you've seen in headers and kernel.S.
