Windows device driver information for Compaq NetFlex-3 Embedded Controller

This driver supports the following driver models: the Compaq NetFlex-3/P Controller, Compaq Netelligent 10 T PCI UTP Controller, Compaq Netelligent 10/100 TX PCI UTP Controller, Compaq NetFlex-3 Embedded Controller, Compaq Netelligent Dual 10/100 TX PCI UTP Controller, Compaq Netelligent 10/100 TX Embedded UTP/AUI Controller, Compaq Netelligent 10 T/2 PCI UTP/Coax Controller, Compaq Netelligent 10/100 TX Embedded UTP/Coax Controller, and the Compaq NetFlex-3/E Controller. The XO laptop, a rugged, energy-efficient, and low-cost notebook computer (used in the One Laptop Per Child project); employs embedded controller technology. This laptop has a small micro-controller device (the ENE KB3700) to manage operations such as battery recharging, as well as other aspects concerned with stopping and starting the notebook. The embedded controller comprises an 8051 micro-controller device, a specialized LPC interface for communication with the processor, and the SPI Flash interface. The SPI Flash ROM then maintains contact with two segments of code and a data manufacturing table.

The embedded controller, used as a KB3700 device, is integral to XO computer management upon CPU inactivity. The KB3700 interconnects with the CPU with EC protocol through an actual LPC interface. The KB3700 also uses the one-wire Dallas protocol to correspond with the battery pack's Maxim DS2756 power gauge. OpenFirmware's ec-dump.fth is able to show a portion of the embedded controller's internal state. Activating the ec-dump code may provide valuable information about the workings of the EC through settings in the EG Register. Firmware active in the XO computer EC originated from two distinct companies, although the technology was changed, and then used, by the OLPC project. OLPC has, as of yet, had little success in persuading these entities to open-source the code used. The OLPC group is currently developing OpenEC, an open-source variation of the incumbent EC firmware. OpenEC is still in prototype stage and is non-functional. It is highly recommended you run a free registry scan for and Compaq NetFlex-3 Embedded Controller errors before installing any driver updates.
