== BIOS ==

The BIOS is stored on the chip "U19" on the motherboard: a Macronix MX25L6445EM2I-10G (marked MXIC MX 25L6445E M2I-10G)

There is also an unpopulated/keyed box header "E16" near the BIOS chip, probably meant for in system programming. Here is the pin mapping:

NOTE: E16 has a very low resistance resistor between pins 1 & 2, thus they are effectively tied together.
