Sometimes you unintentionally PXE boot while you would like to just let the local OS boot. This can happen if you have the boot order mixed up in BIOS or you hit a stray key during POST. Either way here is a helpful little entry to have in your PXE menu.
label harddisk
localboot 0x80
append SLX=0x800×80 – first partition of first HDD
0×81 – second partition of first HDD
0×00 – first floppy drive
