The Dell Latitude CPi A366XT

The Dell Latitude CPi A366XT is an older laptop with 440BX chipset. We're currently evaluating if it's possible to write coreboot support for it.



  • Northbridge: Intel 82443BX (440BX)
  • Southbridge: Intel 82371EB (PIIX4E)
  • Super I/O: SMSC FDC37N958FR
    • The Super I/O also "contains" the embedded controller (EC), which is an 8051 derivate.
  • Audio/video controller: Neomagic NM2200 MagicGraph/MagicMedia 256AV
  • PCMCIA controller: Texas Instruments PCI1225
  • ROM/BIOS chip: AMD AM29F040B (PLCC, 512 KB, parallel protocol, socketed)
    • Unfortunately you can not hot-swap a chip in this laptop, it'll immediately do a hard poweroff if you try it (the EC firmware, which is part of the flash chip, likely doesn't like you removing the chip).
