Not a really good place to start. 8) But for your help & insight, it would have been bad. :) Besides the PCs boot procedure, i wanted to learn more about assembly language (AT&T syntax) and how the FreeBSD Boot Manager works inside. So i've been reading and learning that code. >Hope this helps! That does help a lot. Thanks so much for your hint and two links. Now i think i've got a basic knowledge about the BIOS data area. But reading the code of boot0.s, i got another question as in the following code: main.5: incw dx # Next item addb $0x10,bl # Next entry jnc main.3 # Till done The partition table in MBR only has 4 items, why check for 16 times?? Thanks so much. _________________________________________________________ Do You Yahoo!?
