 It turns out that you can also use an 8Mbit BIOS chip on the S2881. For instance, flashrom supports flashing the SST 49LF080A on the S2881 without problems. Having a 8Mbit chip allows putting a Linux kernel into the BIOS, as described in [http://www.linuxbios.org/Tyan_S2892_Build_Tutorial the S2892 the OLPC way] build tutorial.

		+
		+	The s2881 has 2 HWM chips, each driving a number of fans and temperature sensors. As of SVN revision 2674, the main HWM chip that drives most of the fans (ADT7463) is configured to be in automatic (hardware) fan control mode, based on the temperature sensors connected to it. These are the specific HWM settings:
		+
		+	* fans under automatic hardware control
		+	* fans blow by default at 25% speed
		+	* if any of the sensors goes above 55C (Tmin), the fans start blowing harder to compensate
		+	* if any of the sensors reach 70C (THERM limit), the fans start blowing at full speed
		+
		+	These settings should lead to longer fan life, reduced power consumption, and better protection against accidental fan speed misconfiguration from software. And the machine is a lot less loud under light load.
		+
		+	The original Tyan BIOS had these settings:
		+
		+	* fans under manual (software) control
		+	* fans blow by default at 100% speed
		+	* automatic mode Tmin set to 90C
		+	* automatic mode THERM limit set to 100C
		+
		+	The LinuxBIOS settings should be more ideal for real world deployment, and are a lot safer.
