#The 82443BX is incapable of addressing more than 256MB on a single RAM module, which causes most ThinkPads to max out at 256/512MB. Certain ThinkPads may have 32/64MB soldered on the motherboard, and may allow them to max out at 544/576MB instead.

=== Maximum Memory ===
 
Maximum addressable memory for this Northbridge is 1GB (using four 256MB DIMMs).<br>
 
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.

Intel 82443BX

This is an Intel northbridge.
CPU Host Bridge (PCI ID: 8086:7190)
AGP-PCI Bridge (PCI ID: 8086:7191)

Features


FOOTNOTES [Δ]
  1. The 82443BX is incapable of addressing more than 256MB on a single RAM module, which causes most ThinkPads to max out at 256/512MB. Certain ThinkPads may have 32/64MB soldered on the motherboard, and may allow them to max out at 544/576MB instead.

Linux support

This chipset is supported by recent 2.4 and 2.6 kernels
