ltblball.gif (377 bytes) System Monitoring.   The BH6 has the LM79 hardware monitoring chip.  It monitors system temperature, CPU fan speed, and motherboard voltages.  You can see these values in the Chipset Features Setup in the CMOS setup. Judging from watching the voltages for about five minutes, Abit really has voltage regulation perfected.  Except for the -12V, which changed once and the regulation of which is not as critical as other voltages, the voltages didn't change at all.  On other boards I can see them change frequently.
     I can find no way to set a temperature alarm threshold in the CMOS.  And it's too bad there is no direct CPU temperature monitoring.  I couldn't find any thermisters on the board.  The system must be using the sensor built into the LM79, which is too far away from the CPU to react directly to any CPU temperature change before the CPU overheats.  When I unplugged the CPU fan for as long as I dared, there was no alarm and I did not see the system temperature go up at all.

ltblball.gif (377 bytes) Expansion slots.  The BH6 has 1 AGP, 5 PCI, and 2 ISA slots.  I would gladly trade one of those PCI slots for another ISA slot.  The ISA bus won't die until one can buy PCI printer boards for less than $20.00 and the vast amount of equipment out there with ISA interfaces (scanners, etc.) is gone.  I still occasionally run out of ISA slots on boards that have  three of them.  I have yet to fill four PCI slots in a computer.

ltblball.gif (377 bytes) I/O connectors and cables.  There are PS/2 keyboard, PS/2 mouse, 1 printer, two serial, and to USB along the back of the motherboard (the configuration matches all of the Aopen ATX cases I have reviewed).  The hard disk and floppy drive connectors are along the front per the ATX spec.  I'd like to see a second hard disk cable...  

ltblball.gif (377 bytes) Capacitors.   There are plenty of apparently high-quality 105C electrolytic capacitors, especially around the power components for the CPU and an ample number of bypass, etc. capacitors.  I didn't see any tear-drop tantalums; but I'm not going to try to second-guess the engineers who designed this board.  The board is absolutely stable and that is what counts.

ltblball.gif (377 bytes)  User Manual.  Excellent user manuals are an Abit hallmark.  The manual is extensive, well-written, and full of illustrations and pictures.
