Is this the very first thing that is executed from the hard drive?
Which is copy-ed straight from this file? spcmdcon.sys
Is this considered the MBR or the NTFS bootsector, are they the same?
Im kinda confused after my read, it does not appear to be, if not what is the first thing that the computer reads from the harddrive, I assume its the MBR, is that ALWAYS at the same location on a harddisk?

Disasm of this is found here? http://bootmaster.filerecovery.biz/appnote3.html

Can you write to one while in windows XP/NT /Greater? Link Src?
