Intel 440BX

This is a Intel Northbridge


Maximum Memory

Maximum addressable memory for this Northbridge is 1GB (using four 256MB DIMMs).
No ThinkPad has more then 2 DIMM slots, so are in theory limited to 512MB (with the exception of the 600X, which has an additional 64MB soldered to the systemboard, and can oficially support 64+256+256=576MB). Actual supported memory can be significantly less due to BIOS limits or available DIMM slots.

Linux support

This chipset is supported by recent 2.4 and 2.6 kernels
