Frequently Asked Questions
Q: My system sometimes becomes unstable. How should I check the system?
A: The first thing to do is to check and see if you have any device conflict in
address, IRQ, or DMA. If you are using Windows 95, the Device Manager
is a good place to start. Please consult your operating system manual for
details. Second of all, slowing down the memory timing in the BIOS's
chipset setup section will help the situation, as well. Many memory
modules are not suitable for high performance systems and are probably
the main source of your problem.
Q: What is AGP?
A: AGP (Accelerated Graphics Port) is a new bus architecture for 3D graphics.
The AGP slot eliminates the PCI bandwidth bottleneck by bypassing the
PCI interface and accessing the system memory directly. Currently, the AGP
supports 1X and 2X modes, which yield bandwidths of 264MB/s (at 33MHz
bus speed) and 533MB/s (at 66MHz bus speed), respectively. Compare this
with the mere 132MB/s (at 33MHz bus speed) that you get with the PCI
bus.
Q: Does my operating system support AGP?
A: Currently, only Windows 98 and Windows NT 5.0 will have built-in support
for AGP. Some AGP cards require Windows 95 OSR2.1 or a special driver
from Intel. Please check with your graphics vendor for more details.
Q: Why is the S1590S motherboard NOT working on AMD K6/K6-2 300+MHz
when jumper JP11 is ON?
A: On the motherboard, JP11 is a split-voltage setting. Setting the jumper OFF
(open) allows for separate core and I/O voltages. Newer P55C type CPU's
such as AMD K6/K6-2 require this type of setting. Setting the jumper ON
(closed) gives the CPU only a single voltage control typically for older
P54C type CPU's. Therefore, the motherboard will experience problems if
JP11 is ON.
Q: What is JP11 used for?
A: JP11 is a split-voltage setting. You should leave the jumper CLOSED if you
are using a P54C CPU (non-MMX CPU). Otherwise, you should leave the
jumper OPEN if you are using a P55C CPU or AMD K6 and above.
