    The AGP uses both rising and falling edge of the 66MHz clock and produces 66MHz x 4byte x 2 = 528MB/s data transfer rate. The AOpen AX6L and AX6B MB are designed to support AGP via the new Intel LX & BX chipset.
  • Page 87 A: Even though your system will work fine with this "?" marks, we received many requests about how to eliminate it. AOpen software team spends few weeks to develop an utility AOchip.exe for the convenience of Win95 users. It is very user friendly and can be used on any TX/LX/BX/MVP3/5591 chipset based motherboard, not limited to AOpen products.
  • Page 88 Q: What is ADM (Advanced Desktop Manager)? A: This is a desktop client and server management software developed by AOpen. It is similar as Intel LDCM with some improvement. ADM is not only for corporate network management, it can also be used as system status monitoring utility, for example, CPU fan, thermal and system voltage monitoring.
  • Page 89 Electrolytic capacitor with only 0.15 ohm comparing with 0.7 ohm of Tantalum capacitor. The lower the ESR and higher the capacitance value, the smaller the CPU voltage ripple. Following are the specifications of capacitors that AOpen is currently using: Tantalum: SPRAGUE 100uF, Part number 595D107X06R3C2T, Max ESR is 0.7 at 25 degree 100KHz.
  • Page 90 (the layout). The most accurate way is to use storage scope to measure the CPU voltage directly, but of course, it is difficult for end user to do so. AOpen design team follows Intel, AMD and Cyrix's design specification strictly, it is approved by Intel, AMD and Cyrix.

If the problem still exist, fill out the attached Technical Problem Report Form. Please write down your configuration and error symptoms as detailed as possible.
  • Page 92 Troubleshooting No display. Check all jumper settings to make sure that you have set the proper jumpers, especially those for CPU type, single/dual voltage, CPU frequency and ratio. Check the power cord or power switch of your system. The simple way to identify power failure is to check the CPU fan and the power supply fan.
  • Page 93 Troubleshooting There is display, but can 't boot. Check BIOS Setup if the HDD is set to LBA (more than 540MB) format. Load default setting. Boot system from floppy drive. If pass, the problem should be caused by the IDE cable or HDD itself. HDD Controller Fails, can't detect HDD.
