Application notes for AMI MegaRAC


1) Processors are available with different voltage
requirements. Therefore, Warning and Critical limits
(Mili Volt) must be adjusted for the processor
installed.

For example, if a processor requires X volts the
following might be used:

Warning low limit   = (X - X*0.05)*1000
Warning high limit  = (X + X*0.05)*1000

Critical low limit  = (X - X*0.1)*1000
Critical high limit = (X + X*0.1)*1000


2) This MegaRAC SDK port works with revised MegaRAC
firmware that increases the flexibility of SDK. 

The following rules apply to both Warning and Critical
limits.

a) If a pair of Limits are zero, they are not used to
generate events. For example, IF (Warning Low Limit == 0)
AND (Warning High Limit == 0), no warning events will
be generated for the associated sensor. This makes it
possible to skip setting Warning or Critical limits.

The user may not want both kinds of limits.

b) If a Lower Limit is greater than zero and the
associated Upper Limit is zero, the Upper Limit is
not checked. For example, IF (Warning Low Limit > 0)
AND (Warning High Limit == 0), the Warning High
Limit will not be checked. This makes it possible
to only set a lower limit that is greater than zero.

Fans usually have only a lower limit.

c) If a Lower Limit is less than zero and equal to
the associated Upper Limit, the Upper Limit is not
checked. For example, IF (Warning Low Limit < 0)
AND (Warning Low Limit == Warning High Limit), the
Warning High Limit will not be checked. This makes
it possible to only set a lower limit that is less
than zero.

This can be used for sensors that usually supply
negative values.

How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

  • Expand the archive file (if the download file is in zip or rar format).

  • If the expanded file has an .exe extension, double click it and follow the installation instructions.

  • Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.

  • Find the device and model you want to update in the device list.

  • Double-click on it to open the Properties dialog box.

  • From the Properties dialog box, select the Driver tab.

  • Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
