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