chaintech zenith 9cjs CBOX3

[glenmo]

the 9cjs came with a 5.25 bay that provides card slots, front usb and firewire, and an LCD POST code display. it's called the CBOX3, and it connects to the motherboard in various places.

in windows, you can use chaintech's proprietary software to get the LCD display to show the cpu's current temperature.

knowing that linux has a directory for every system device in /dev,
a) how would i determine which directory represents the POST code display, and
b) what could i do to get that device to display the cpu temp?

thank you for looking at my post, i hope the question isn't too moronic...

Do you know what LCD controller the Chaintech device uses? Is the LCD device itself USB powered?

LCDproc is very nice if it supports your screen.

i replied, but it didn't show up...

By chance does anything related to the display show up on lspci? Have you ever cracked open the device to look at the screen?

[glenmo]

the LCD is a simple, two digit display. it's not usb powered -- it connects directly to the mobo. there's a picture here:

i wouldn't feel comfortable cracking open the device... here's a pic of the back:

[glenmo]

is there some problem with posting replies with pictures? i posted a picture of the CBOX3, but it didn't show...

anyway -- i'll have to check lspci and see... do you know what it would look like if lspci finds it? the screen is a simple 2-digit lcd, nothing special about it. it connects directly to the mobo... you can see pics of it (front & back) here

i'll get back to you on the lscpi...

connects directly to mobo -- not usb.

no ideas yet?

i figured it could probably use some kind of command line program to get the cpu temp, then pipe that printout into the device somehow...

is there a cmd line application that reads cpu temp? then all i would have to do is find the device in /dev... and... um... well, we'll burn that bridge when we get to it, i guess...

Not sure yet.

Check out sensors/lm-sensors for reading temperatures.
