viaenv -- VIA VT82C686A/VT8231 Hardware Monitor and Power Management Timer
SYNOPSIS
viaenv* at pci? dev ? function ?
DESCRIPTION
The viaenv is an envsys(4) compatible driver for the Hardware Monitor and the Power Management timer in the VIA VT82C686A and VT8231 South
Bridges.
The device has 10 sensors:
Sensor Units Typical Use
TSENS1 uK CPU temperature
TSENS2 uK System temperature
TSENS3 uK ?
FAN1 RPM CPU fan
FAN2 RPM System fan
VSENS1 uV DC CPU core voltage (2.0V)
VSENS2 uV DC North Bridge core voltage (2.5V)
Vcore uV DC Internal core voltage (3.3V)
VSENS3 uV DC +5V
VSENS4 uV DC +12V
Sensor data is updated every 1.5 seconds.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

sort -nr --key=1 ....

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
