Thunder i7500 (S2720) FAQ Updated 07/17/03
Are there any special considerations when installing Linux?
- Is there TYAN System Monitor support for this system board?
Yes! Please go to the following page for more details and software download.
- What kind of power supply is recommended for the S2720?TYAN recommends
EPS12V power supplies, exclusively. The use of a non-EPS12V supply will damage the board, and will void your TYAN warranty! Please do NOT use an ATX12V supply!
Check here for the recommended listings.
System power consumption = S2720 power consumption + PCI cards, IDE drives, SCSI drives, Serial port devices, Floppy drive, USB devices, Keyboard, Mouse and etc
S2720 major board level components maximum power ( in mA ) : see here
( All local switching regulators are assumed to have 80% efficiency. )
- Why will my Adaptec 2200S SCSI Raid card not allow my system to POST when it is installed?Adpatec has released a new firmware flash update to address compatibility issues with the Intel i75xx chipset. The updated firmware can be found at:
- Is there any power supply, chassis, or cooling recommendations?Adpatec
has released a new firmware flash update to address compatibility issues with the Intel i75xx chipset. The updated firmware can be found at:
- I set the computer's "power-interrupt" option to "AUTO-ON", but after the power interrupts, the computer stays off when the power is back. Why?The computer should turn on automatically if "power-interrupt" option is set to be
"AUTO-ON". However, there is a preset scenario where if power interrupts, computer turns off, and someone presses the power button for 4 seconds or more, the computer will not turn on
automatically even though it is set to "AUTO-ON".
- What type of chassis is recommended for the S2720?TYAN recommends
chassis' that conform to the SSI EEBv3 form factor. Other chassis' are not supported, and could lead to shorts on the PCB! Check here for the recommended listings.
- Should I take any special precautions when connecting the power to the S2720?Please use the following order for power connection:
a. 8-pin connector
b. 24-pin connector
c. main power cord.
- Are there any special considerations regarding processor installation?
Due to the design of processor socket, the ZIF socket arm needs to pass 90° in order for the processors pins to correctly "seat" in the socket's holes.
- How can I tell if I have a PWT or a PWTu?The pictures show a difference
between the two types of Power Wind Tunnels from Intel. The closed top (left image) is the original Intel PWT and the open top PWTu (right image) is the new solution from Intel.
- I'm trying to mount my Intel PWT with no success. How can I get the PWT to work with this motherboard?The original design of this product did not incorporate the PWT in the keep out specs. Certain modifications had to be made later to accommodate the PWT into
the design. If you have the RJ45 connector that are the exact same size (left image) then the original PWT from Intel will work with your motherboard. However
if you have the version where one RJ45 connector is longer than the other (right image) then no PWT from Intel will work for your system.
- Are there any special precautions regarding memory installation?
- You must install DDR memory modules in pairs. Be sure to refer to the
S2720 User's Manual (pgs. 11-13) on how to install memory into the S2720.
- Although the chipset supports x4 or x8, these memory types (x4 and x8) CAN NOT be mixed. You must use one or the other.
- Both DDR200/PC1600 and DDR266/PC2100 are supported.
- Registered PC2100 DDR memory can be used on the S2720, but the memory will only run at PC1600 speed. This is because the DDR memory must match the CPU Front Side Bus (FSB) speed, on S2720.
- If you use the current production BIOS, you must first install the memory modules from the DIMM closest to edge of the board, then go inward,
towards the center of the board. If you use the current Beta BIOS (before 3/21/02), you must first install the memory modules from the DIMM
farthest from edge of the board, then go outward, towards the edge of the board.
- Are there any special considerations regarding the installation of Intel's chipset INF driver?Upon installing the Intel chipset INF driver, if the onboard SCSI is enabled, there will be a pause of approximately 5 minutes when the installation reaches 90%
complete. This is normal. If the onboard SCSI is disabled, the installation should proceed without this pause.
- Are there any special considerations regarding the installation of PCI devices in PCI-X slots?
- The lowest speed PCI devices will determine the overall flow rate of the PCI devices.
- The first two PCI-X slots (closest to center of board) support PCI-X devices at 66MHz and conventional PCI devices at 66/33MHz. The third and fourth
PCI-X slots support PCI-X devices at 133/100/66MHz and conventional PCI devices at 66/33MHz.
- Are there any special considerations regarding the installation of the ATA-100 driver?Intel does not plan to support this feature. The ATA-100 driver is an optional feature provided by TYAN. Please read the pdf for additional information.
- What are the ramifications of installing the Beta BIOS?
For the Beta BIOS released before 3/21/02, following issues have been found:
- To change the CPU speed in the BIOS, use Backspace key to delete the default speed, and then insert the appropriate speed.
- After inserting the appropriate CPU speed, safe the changes, then do a cold boot, then power down, and then power on to enable the new CPU speed setting.
For RedHat 7.2, currently only LILO loader is supported. GRUB loader requires a BIOS fix which is currently under development. Please view the following pdf document
for additional information.
How can I enable DMA in Red Hat 7.3?
You need to use the stable 2.4.18 kernel instead of Red Hat's 2.4.18-3 kernel. Then use the command "hdparm -d1 / dev/hd<x>"
Are there any issues related to the OS?
Operating System Status Update
Operating systems status is documented below. Operating systems have been categorized into three groups based on testing at Intel. The three groups are:
i. Latest released version has no known issues
ii. Latest released version requires patch(es). Next release to include patch(es).
iii. Known issues prevent installation and / or booting
In the event that problems are encountered with any of the links or this summary is not consistent with your findings, please contact your Intel Field representative with any questions.
Latest released version has no known issues:
· Speed detection issues with processors > 2.0 GHz fixed in Win2K SP3

Latest released version requires patch(es):
Linux 7.2 - Redhat*
- the most recent Redhat 7.2 kernel:
- the most recent Linux Kernel:
- the OS (kernel version 2.4.9-21) WILL install, but many devices will not work correctly because the P64H2 IOAPICs are not handled correctly by the OS
- for the patches [named: ptf7619c and ptf7716a]: here
- No known issues with Solaris 8 10/01 Version.
- Order the CD for this version here.
- Versions of the OS previous to this CD-version have Intel® Netburst Micro architecture support issues.
