OCW published a review on the ECS PF88 with AS9 upgrade board

ECS made a bold move to integrate an upgrade slot with a base board allowing the board to adapt to future CPU socket types that uses a common south bridge.

ECS PF88 main board is based on the SiS LGA775 chipset, SiS 656 NB and SiS 965 SB. The board supports the Intel P4 LGA775 socket and includes 4 slots of DDR2 667 memory, a 1066FSB, SATA2, GigaLAN, 1394a Firewire.
