[Solved]error C2415: improper operand type

[melgmry0101b]

Hi everyone,
I am compiling my OS in MSVC 2005.
Now i want to modify the value of Code Selector (CS) to fit my needs.
When i use this code in inline assembly in MSVC 2005 :

Code: Select all

mov ax, 0x33 ; the value that i want
mov cs, ax   ; moving the value to Code Selector < here is the error >

the error list in MSVC shows this error to me :

error C2415: improper operand type

and i read the documents of MSVC on MSDN , and it shows that i should use /G1 or /G2 in the command line.
I used it but i still get the error.

Can anyone help me to repair this problem?

Thanks in advance

You can't mov a value to cs. You must use a jmp, call, ret or iret instruction.

How?

This deserves no other reply than RTFM. Especially since you can't have done that properly in the time you posted the reply.
