Pci Speed Jumper - TYAN THUNDER LE-T User Manual

2.3 PCI Speed Jumper (J60)*
With this jumper, the PCI bus can be set to either 33 or 66MHz. Please check the PCI card speed
before setting J60. Setting the PCI bus to 66MHz, while the PCI devices can only run at 33 MHz,
will cause those PCI devices to run past their designated bus speeds.
Pay careful attention to the speed of the devices that you will be installing
into the PCI slots, and use that information to set J60 accordingly. Setting
the PCI bus to a speed higher than your PCI device can handle will
damage the PCI device.
NOTE
Tyan takes no responsibility and will not be held liable for damage related
to the operation of the PCI device using different settings from those of the
PCI device manufacturer's specified device settings.
* Onboard Adaptec 7899W, if available on your Thunder LE-T, runs on a 66MHz SCSI bus.
After setting the SCSI bus to 33MHz, the Adaptec 788W will be downgraded to 64-bit / 33MHz
speed.
