1.0 - Why is the S1590S motherboard NOT working on AMD K6/K6-2  300+MHz when jumper JP11 is ON?
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.

1.1 - My AGP Video has an Intel i740 chipset and gives me problems when I plug it onto this motherboard, why?
There is a known incompatibility with the Intel i740 chipset and the VIA Apollo chipset on the motherboard. In addition, Windows NT 4.0 does not support Intel's i740 and older chipsets.   Such a combination will definitely cause a conflict.  One solution to this problem is to download VIA´s AGP driver (AGP driver ver. 2.6 or later).  Click [HERE] to download file at VIA´s website.

1.2 - What is "Memory Clock Speed" used for?
The Memory Clock Speed deals with the clock speed relationship between DIMM and CPU.   If you are using an AMD CPU that runs at 100MHz-bus speed and are NOT using PC100 SDRAM, you should set the jumper to AGP clock 2-3.   Otherwise, if you are using PC100 SDRAM, then you should leave the jumper at CPU clock 1-2.  For all other CPU's, the jumper should be set to CPUclock 1-2.

1.3 - What are the x1.5 and x2 multiplier jumper settings? They are not mentioned in the manual.
For the 1.5x jumper setting - JP8 is OFF, JP9 is OFF, and JP10 is OFF
For the 2x jumper setting - JP8 is OFF, JP9 is ON, and JP10 is OFF.

1.4 - What is pin#1 for J3, J4, J5, and J6?
Pin#1 for the all the jumpers above face towards the PCI slots.

1.5 - Where is pin#1 for JVBAT1?
Pin#1 for JVBAT1 is the one closest to the VIA MVP3 chipset.

1.6 - What is JP11 used for?
JP11 is a split-voltage setting.  You should leave the jumper CLOSED if you are using a P54C CPU.  Otherwise, you should leave the jumper OPEN if you are using a P55C CPU.

1.7 - Does the motherboard support x2 AGP?
Yes, the S1590S Trinity 100AT supports x2 AGP.

1.8 - What drivers do I install from the CD-ROM provided with the Trinity S1590 Motherboard?
Inside the CD-ROM provided with the Trinity motherboard are Win95, Win98, and WinNT 4.0 drivers for VIA MVP3 chipset and are located in the VIA folder.

    The "agpvxd" folder will install driver support for AGP video.  NOTE: this driver is for Win95 users only, however, some Win98 users may need to install this driver who are having conflicts in Device Manager.  There are no drivers for WinNT 4.0

    The "Bmide" folder will install driver support for VIA IDE Busmaster.  NOTE: this driver is for Win95 and WinNT 4.0 users. Win98 users normally DO NOT have to install this driver; Win98 has built in VIA IDE Bustmaster driver when installed originally.  Install only if you are having conflicts or exclamation marks with Hard disk controllers in Device Manager

    The "viareg" folder is for "VIA Power Management Controller" and "VIA PCI to USB Universal Host Controller".  NOTE: this driver is for Win95 users. There are no drivers for WinNT 4.0.  No need to install for Win98 users.

    The "virq13 or virq11" folder will install "VIA PCI IRQ Routing Miniport Driver".  NOTE: Enable "OnChip USB" in BIOS Chipset Features setup menu and Enable "Assign IRQ for USB" in PNP/PCP Configuration Setup menu. NOTE II: this driver is for Win95 users only, however, some Win98 users may need to install this driver who are having conflicts in Device Manager.  There are no drivers for WinNT 4.0

1.9 - When Windows 95 restarts for the first time I get the following message:  "Device IOS failed to initialize.  Windows Protection Error.  You must reboot your computer."  How do I fix this to get into Windows 95 normally?
Follow the following link to download the patch file for this problem:

2.0 - What are JP7  and JP14 for?
JP7 and JP14 are provided on some S1590 versions.  The jumpers control the power supply feeding the L2 cache.  The two jumpers regulate the power supply voltage in order to provide the circuitry with ~3.3V for normal operation.  Basically, if you have an AT power supply, set both jumpers JP7 / JP14  CLOSED or ON.  If you have an ATX power supply, set both jumpers  OPEN or OFF.  .

2.1 - Does the S1590S support the AMD K6-3 processor?
Yes!  S1590S DOES support the AMD K6-3 processor (as well as K6-2 up to 475MHz).

2.2 - When I shut down Windows 95, there is no message saying "it is now safe to shut off your computer".  What should I do?
Win 95 shutdown screen problem can be solved by changing the Video Off Method to "Blank" instead of "V/H sync + Blank" under the Power Management Setup menu.  Enable the OnChip USB under the Chipset Features Setup menu, and enable Assign IRQ for VGA under PNP/PCI Configuration in the BIOS menu.

2.3 - What are those FUNNY SOUNDS coming from my 1590 motherboard?

If you are experiencing a "musical" (3-4) tone beep coming from the case speaker, this is the "CPU Warning Temperature" basically telling you the CPU or the inside of the computer case is getting warm. Nothing to be worried about, but rather to inform you. You can simply increase the thermal degree's in the BIOS under the Chipset Feature Setup menu so the CPU sensor on-board doesn't trip so easily and set the alarm off. Or you can disable it all together in the BIOS under the Chipset Feature Setup menu.

2.4 - My board is missing jumpers JP7 and JP14.  What should I do?
Most newer versions of the S1590 motherboard DO NOT have jumpers JP7 or JP14
- the motherboard autodetects the power supply and provides the correct settings automatically.  Therefore, if your board is missing jumpers JP7 and JP14, there is no need for concern.

2.5 - After I start up the Hardware Monitoring software in Windows, how do I get rid of the periodic lines flashing across my video display?
Go into the bios and the Power Management Setup menu and change the line Video Off Method from DPMS Support to Blank Screen or the selection V/H SYNC + Blank.

2.6 - I get the following message when flashing my S1590 BIOS: "The programs file's part number does match with your system. Are you sure to program Y\N?"  What should do?
When prompted, it is OK to continue with the BIOS programming by agreeing.

2.7 - I don't get full colors with my AGP or PCI video card in Windows 95/98.
