Hello, All!

I can't assemble next code:

// Compute offset for GDT and IDT
        xor %eax,%eax
        mov %cs,%ax
        shl $4,%eax
        add $_GDT,%eax
Trouble:
        mov %eax,$GDTDescriptor

Asm error "suffix or operands invalid for mov"

But it assemble this code in form

// Compute offset for GDT and IDT
        xor %eax,%eax
        mov %cs,%ax
        shl $4,%eax
        add $_GDT,%eax
Correct:
        mov %eax,GDTDescriptor

But I want relative address here! Help me with real offset of GDTDescriptor
value.

With best regards, Sergey Gotsulyak.  E-mail: sergo AT pisem DOT net
