ADDENDUM

Addendum for all Thunder LE S2510 Manuals

Depending on the LSI SCSI chip on your Thunder LE motherboard, you will need to
NOTE: set certain jumpers and BIOS settings accordingly, in order to ensure proper opera-
tion of your Thunder LE.

How to tell which LSI SCSI chip your Thunder LE has:

How to change the PCI and SCSI settings...

Step 1:

J60
* If you have an LSI 53C1010-33 chip, close J60
* If you have an LSI 53C1010-66 chip, open J60
* See mini-map on the right for location of J60
NOTE: If you install a 33MHz PCI device, both PCI slots
and the SCSI ports will run at 33MHz.

Step 2:

In the BIOS, under Onboard Device Configuration (inside the Advanced Con-
figuration screen), set Onboard LSI SCSI to Enabled.

The onboard SCSI controller feature can be changed using this
option. Please note that you will need to disable SCSI in
order to use the PCI slots at 66 MHz. Similarly, you will need
to close J60 so the SCSI will run at the proper speed of 33
MHz (see p. 13 for details). Also check the Tyan website for
