Frequently Asked Questions
Q: How to install Windows 95 USB driver?
A: If you are Win'95 OSR 2.0 user (.950B, shows "PCI Universal Serial Devices"),
you may obtain USBSUPP.EXE from Microsoft or your OEM system provider
for installing Microsoft USB supplement which will create "USB Supplement to
OSR2" in the list of Add/Remove program tool under Control Panel. After
above installation, please run AOchip.exe provided by AOpen to create USB
Controller under Device Manager.
If you are Win'95 OSR 2.1 or 2.5 user, only AOchip.exe installation is
necessary.
If you are Win'95 retail user (.950 or .950A), there is no direct upgrade path
available from Microsoft at this moment. It is expected to be implemented
under Windows'98.
Q: What is jumper-less mainboard?
A: Pentium II VID signal and SMbus clock generator provide CPU voltage auto-
detection and allows user to set CPU frequency through CMOS setup, no
jumper or switch is needed. The correct CPU information is saved into
EEPROM, with these technologies, the disadvantages of Pentium base
jumper-less design are eliminated. There will be no worry of wrong CPU
voltage detection and no need to re-open the housing if CMOS battery loss.
The only jumper left is to clear CMOS, which is a safety hook if you forget the
password. AOpen AX6L/AX6LC/AX6B/AX6BC does implement jumper-less
design.
Q: What is battery-less mainboard?
A: AX6L/AX6LC/AX6B/AX6BC implements EEPROM and special circuit (patent
applied) that allows you to save your current CPU and CMOS Setup
configurations without the need of battery. The RTC (real time clock) can also
keep running as long as power cord is plugged. If you lose your CMOS data
by accident, you can just reload the CMOS configurations from EEPROM and
the system will recover as usual.
Q: What is the benefit of using Resetable Fuse?
A: The traditional pico-fuse needs to be replaced once it is burned due to any
abnormal surge current. It has to be replaced by qualified repairing engineer
which is cost & time consuming.
motherboard starts to introduce new "Resetable" fuse, which is "PolySwitch",
to protect your keyboard & USB circuit. When there is surge current, this
PolySwitch will reach high impedance within few m/seconds so that the circuit
becomes opened. PolySwitch will be recovered to its original stage after surge
current disappeared & the system is being cooled down for a while.
