Appendix A Frequently Asked Question Note: FAQ may be updated without notice. If you cannot find the information that you need in this appendix, visit our WWW home page, (address: http://www.aopen.com.tw) and check the FAQ area and other new information. Q: How can I identify the mainboard BIOS version? A: The AOpen mainboard BIOS version appears on the upper-left corner of the POST (Power-On Self Test) screen. Normally, it starts with R and is found in between the model name and the date.
Frequently Asked Questions Q: Why the AOpen mainboards (MB) do not have cache module expansion slot? A: Faster CPU speed requires more difficult and complex MB timing design. Every trace and components delay must be taken into consideration. The expansion cache slot design will cause 2 or 3ns delay in PBSRAM timing, and the extended trace length to the cache module through the golden finger will further delay the timing by 1 or 2ns.

A: The traditional PIO (Programmable I/O) IDE requires the CPU to involve in all the activities of the IDE access including waiting for the mechanical events.
Frequently Asked Questions CPU, and slow down the CPU speed as well as warning when temperature is high then a predefined temperature. (Normally, 55 degree C.) Q: What is the Ultra DMA/33? A: This is the new specification to improve IDE HDD data transfer rate. Unlike traditional PIO mode, which only uses the rising edge of IDE command signal to transfer data, the DMA/33 uses both rising edge and falling edge. Hence, the data transfer rate is double of the PIO mode 4 or DMA mode 2. (16.6MB/s x2 = 33MB/s).
Frequently Asked Question Q: What is the performance of Ultra DMA/33? Do we need special driver? A: You need driver to activate DMA/33, there are now driver from INTEL or you can use driver in the Windows 95 Memphis, which can recognize South Bridge PIIX4. We got the mass production sample Quantum Fireball ST1.6A, following are the test result.
Frequently Asked Questions Q: What is the memory performance improvement of TX chipset? A: Following is the compare table of TX+SDRAM, VX+SDRAM, TX+EDO, HX+EDO and VX+EDO.
Frequently Asked Question Q: Why does the system fail to go into suspend mode under Win95? A: This problem may be caused by your CDROM settings. The CDROM Auto Insert Notification of Win95 is dafault enabled, the system will continue to monitor your CDROM, auto-execute application when a CD diskette is loaded, and prevents the system from entering into suspend mode. To resolve this, go into Control Panel è System è Device Manager è CDROM è Setting, and disable the "Auto Insert Notification" function.

Tip: There are many useful information in our homepage, such as jumper settings, latest BIOS, drivers, and more FAQs. Visit our homepage to see if there is answer of your problem.
Troubleshooting the problem is your add-on cards or peripheral. try to reinstall the add-on cards one by one to find out which card is causing the problem. 4. Check the monitor and VGA cable. Press the key to enable/disable the Num Lock function. If the Num Lock LED works properly, this indicates that your CPU, SIMM and BIOS bootup sequence are properly functioning. The problem may be caused by your VGA or monitor. Unstable system or HDD, HDD with bad sector.
Troubleshooting 8. If your CPU bus frequency is 66MHz, set the CPU external/bus frequency to 60MHz, but leave the CPU core/bus frequency ratio unchanged. Normally, CPU with 66MHz bus frequency works properly at slower speed, e.g., 60MHz. This will help you identify if the CPU is remarked or if the mainboard or add-on card is unstable at 66MHz. Keyboard, Mouse, Printer or Floppy is not working properly. 1. Check the cable and bracket.
Troubleshooting 5. Disable the external cache (2nd level cache) and system BIOS cacheable or VGA BIOS cacheable parameters in BIOS. Refer to Chapter 3 "Advanced CMOS Setup" section. Some applications has trouble at higher system speed. 6. Visit our WWW home page, (address http://www.aopen.com.tw), check the FAQ area (frequently asked question) and download the latest BIOS, try again with the latest BIOS.
