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:
| U19 Pin | E16 Pin | Function |
|---|---|---|
| 1 | 1/2 | CS# |
| 2 | 5 | SO/SIO1 |
| 3 | WP#/SIO2 | |
| 4 | 8 | GND |
| 5 | 3 | SI/SIO0 |
| 6 | 7 | SCLK |
| 7 | NC/SIO3 | |
| 8 | 6 | VCC |
NOTE: E16 has a very low resistance resistor between pins 1 & 2, thus they are effectively tied together.
