X86BOOT (Compact 2013)
3/26/2014
This configuration option specifies whether a jump instruction is inserted at the x86 reset vector address. Optionally, you can specify the target jump address.
Syntax
X86BOOT = OFF | ON | address
Parameters
- OFF
This parameter, which is the default, ensures that no jump instruction is added to the run-time image.
- ON
This parameter adds a jump instruction to the run-time image at the reset vector location. By default, this jump instruction branches to the beginning of the kernel run-time image address.
- address
This parameter, which is a hexadecimal address, adds a jump instruction to the specified address at the reset vector location in the run-time image.
Remarks
If you specify a target jump address, the low-order word subtracts 0xFFF3, as shown in the following code example.
jump_offset = LOWORD(x86boot) - LOWORD(0xfff3);
If you select the ON parameter, the same operation is applied to the startup address and used as the jump_offset.
