SIM socket ?
By itself the SIM socket does not do anything. You need a 3G modem in the miniPCI express socket to get connectivity.
miniPCI Express ?
This is a new standard for small size radio modules, using PCI Express and USB 2.0 connectivity. On ALIX, only USB 2.0 connectivity is supported. Some manufacturers of radio modules:
• Ericsson
• Novatel
• Option
• Sierra Wireless
•wi-fi cards using PCI express will NOT work !
•Modem modules based on Qualcomm chipsets don't seem to work reliably with the AMD CS5536 USB controller - consider limiting to 12 Mb/s USB 1.1 mode. Ericsson modules don't observe the reset signal, difficult to get a proper reset on reboot.
BIOS update note
Board ID has been changed, flash updater will look for alix5.bin . Latest BIOS = v0.99j.
Changes from alix6e
• Enhance resistance to injected RF energy.
• Change chassis ground connections to enhance resistance to ESD / burst.
• Disconnect miniPCI express pins 30 and 32 (SMBDAT / SMBCLK).
• Reset controlled by USBEN2.
• Shift miniPCI connector to fit larger Wifi modules (dcma82 / dnma92).
