Supports the following processors:
- Intel Mobile Pentium II
- Intel Mobile Pentium III
Supports the following memory modules, up to a maximum of 1024 MB:
- PC-133¹ (will be limited to PC-100 speeds)
- PC-100¹
- PC-66¹
- EDO 60ns
AGP revision: 1.0, 1x/2x
Front Side Bus (FSB): 66/100 MHz
Paired with the following southbridges:
- Intel 82371AB southbridge
- Intel 82371EB southbridge

FOOTNOTES [Δ]

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.

This chipset is supported by recent 2.4 and 2.6 kernels
