Solid State Drive

The solid state drive on the Eee is powered by a Silicon Motion SM223 CF flash card controller and 4x NAND flash chips from various manufacturers.

NAND flash found:

• Hynix 8Gbit HY27UG088G5M
• Intel 8Gbit 29F08G08CANB2 (found on mine)

BIOS Chip

For a little while there was confusion how the BIOS was stored. Speculation about parts of the SSD could be used for the BIOS, integrated chipset BIOS, or a unknown IC-chip.

Turns out the BIOS chip was covered by a adhesive label and the part number is Winbond 25X40VSIG. It features a 8-pin 512K serial flash.
