Die Herstellerseite kann unter http://www.ecs.com.tw aufgerufen werden.
Sucht man aktuell jedoch nach Handbüchern für dieses Mainboard, so stößt man immer auf tote Links.
Folgende Funktionszusammenfassung fand ich heute im WWW:
ZitatAlles anzeigen1. CPU SUPPORT
The K7S5A supports Athlon XP inc Tbred up to 2600+, Athlon inc Tbird, and Duron inc Morgan cores.
There is no official support for 333Mhz FSB Athlons but it may be possible to get them working.
2. SPECS
ECS Site for the K7S5A
3. BIOSes
The official BIOS is lacking in overclocking features, to get non-standard FSB speeds you will need to flash an unofficial BIOS. You can get one from this page, (Cheepobios). I am running this BIOS and it is solid as a rock. FSB's you may be interested in are 112/112, 138/138, 143/143, 147/147 and 150/150 (CPU/Mem). It is not recommended to use an asynchronous CPU:MEM as the performance is well, sucktacular.
Note on Cheapobios: There have been reports that this BIOS destroys the board's bios chip. Exercise caution.
Release notes for the different BIOS versions are here.
All BIOSes will correctly run an Athlon XP, but cosmetically the number displayed at startup will only be correct as of 010911 (and later) BIOS revisions.
4. FLASHING THE BIOS
The usual warning: If it ain't broke, don't fix it. I'm not responsible if you screw up. BIOS mis-flashing can render your board useless.
You'll need the amiflash utility, and the BIOS image itself. Both are contained in the zip file you downloaded.
I'll assume you know how to unzip the files.
For DOS, 9x and ME, you'll be able to boot into DOS. Windows 2000 and XP users will need a DOS boot disk from http://www.bootdisk.com , there are several downloads available for the purpose of BIOS flashing. You can also burn a boot CD if you don't have a floppy drive.
At the DOS prompt, you'll need to get to the directory where you unzipped the files. eg. for C:\windows\desktop type "cd\windows\desktop" at the prompt.
Type "aminfxxx xxxxxx.rom" replacing the xxx's with the correct numbers. You can check the filenames by entering the "dir" command at the prompt to see the directory contents.
Press enter to run the utility. Once it is complete the system will reboot.
You'll get a ""CMOS settings wrong.... " error, this is normal, and a "Wrong size" error for unofficial BIOSes, this is also fine.
Press F1 to enter the BIOS and F10 to save changes.
note 1: If you have an NTFS drive, you'll need to put the files on CD.
note 2: Flashing from a floppy is not recommended because floppy disks could easily contain bad sectors (more prone to errors, which you don't want).
5. CLEARING THE CMOS
1. Unplug the power
2. Remove jumper JP4 and place it on pins 1-2
3. Wait 5 seconds or so
4. Put back on pins 2-3
5. Plug power back in and start
6. WHY IS MY ATHLON XP 1.67 RUNNING AT 1.25Ghz
The board defaults to a FSB speed of 100Mhz, set this to 133Mhz in the CPU PnP area of the BIOS.
7. DRIVERS
The SiS chipset has far fewer driver releases than VIA boards, but the latest drivers for AGP, Audio and LAN can be had from SiS's website.
If you are using Windows XP, the default drivers provide better performance than the ones you can download.
8. CONNECTING THE CASE LEDS
9. POWER SUPPLY
To run this board you want at least a 300W power supply (or a very good quality 250W). Many issues with this board can be traced back to a too-small power supply. A 400W or more PSU from a reputable name like Antec or Enermax is the best bet for reliable operation. More information is here.
OVERCLOCKING - THE MULTI MOD
This will allow you to change the clock multiplier of the CPU. link
OVERCLOCKING - THE VCORE MOD
This will let you change the VCore of the CPU. link
OVERCLOCKING - THE VMEM MOD
This one lets you adjust the voltage of the RAM. link
OVERCLOCKING - FSB ADJUSTMENT
Once you have an appropriate BIOS, you can adjust the FSB speed. Keep moving it up until the system doesn't boot, then see the section on clearing the CMOS above when you get a blank screen.
OVERCLOCKING - THE VChipset, DDR & AGP MOD
See this page for more info.
OVERCLOCKING - MONITORING
I recommend Motherboard Monitor to check your voltages and temps. The settings to use are:
Sensor 1 = Sis950/ITE8705-2 = Case Temp
Sensor 2 = Sis950/ITE8705-3 = CPU Temp
Sensor 3 = Sis950/ITE8705-1 = Null. This is a 'ghost' reading.
Voltages Sensor = Sis950/ITE8705-4
11. ISSUES - THE 3D GAME FREEZE
This is the most common problem. Symptoms are usually:
Freeze/lockup when using 3D games or apps, usually after 10mins but sometimes after extended periods of 1 hour or more.
This mostly occurs with SDRAM systems, especially when both slots are populated and/or the system is running at 133/133.
Things to try in order:
Check components are adequately cooled
Decrease FSB to 124/124 (requires CheepoBios)
Use only 1 stick of RAM, try swapping slots also
Try moving devices to other PCI slots
Do the heatsink mod
Reinstall OS
Replace PSU
Replace SDR-SDRAM with DDR
RMA board.
Fiddling with the BIOS settings does not usually fix the problem. If the system is stable at 124/124, your RAM is at fault, your PSU is at fault, or the chipset is not adequately cooled and you need to do the heatsink mod.
