High power radio cards
Earlier production boards don't react kindly to the abuse dished out by high power radio cards.
Change the following component values:
ALIX.2C
R83 = 2.2K ohm (was 1.0K / marking 01B)
C98 = 4.7 nF (was no stuff)
ALIX.3C
R73 = 2.2K ohm (was 1.0K / marking 01B)
C93 = 4.7 nF (was no stuff)
2.2K ohm resistors are marked 222 (5%) or 34B. Parts can be supplied to customers on request.
Operating system compatibility
Please keep in mind that ALIX.2 and ALIX.3 boards do not include a keyboard controller. Some
boot loaders may hang and need to be modified.
For best performance, include support for AMD Geode LX / CS5536, and use a current driver for
the Via VT6105M LAN controller (which supports TCP/IP checksumming and byte aligned
transmit buffers, unlike earlier Via Rhine parts).
Reboot is best triggered by port 92h.
FreeBSD
Current versions of FreeBSD may panic due to issues in the EHCI configuration. Disable EHCI
driver if problems appear.
FreeDOS, MS-DOS 5.0
Tested ok, booting from CF card.
Linux
Try

Time drift ? Depending on the system you may need to install the package adj-timex.
NetBSD
Not yet tested.
OpenBSD
OpenBSD 4.0-stable and later versions should support AMD Geode LX.GPIO supported by
glxpcib(4) driver. Please upgrade to BIOS 0.99 or later to resolve problems with the serial console.
ALIX system board
for a kernel preconfigured with Geode LX drivers.
