Position of power-on pins - looking for Aptiva 2174 manual

Hello,

Anyone is kind enough to tell me the positions of the HD LED, power-on
pins
on the motherboard of Aptiva model 2174-E86 (CPU AMD Athlon K7 650MHz
slot A, and 3 SDRAM slots).
I searched IBM support group, and can not see any manuals listed for
2174.
This directory that I get from Googling seems empty.

Thank you,
/Van
