Question about Dell XPDFK Precision Workstation T3500 Motherboard Supported Processors Intel Xeon 6Core (X5670
How do I reset the cmos on this motherboard
This depends on what you're trying to do. If you've changed something in the BIOS itself and it no longer works, but you can't remember the default, enter the BIOS and press <Alt><F>. If you have a password on the BIOS that you can't remember, there is a jumper on the board itself that will clear the password. There is also a jumper to clear the NVRAM, which may help you.
The schematics for the jumpers are here: http://support.dell.com/support/edocs/systems/wsT3500/en/SM/a_sysbd.htm
If you've never used a jumper, you're looking for a little plastic bit on the motherboard. If you pull up on this plastic bit, (fingernails are very helpful here) you'll see two gold pins sticking up off the motherboard. This is a jumper. To deactivate the password or clear the NVRAM, remove the appropriate jumper connector (the plastic part) and power up your system for about 10 seconds. Then turn it off, replace the jumper and cross your fingers.
Hope this helps!

To reset the CMOS the easiest way is, remove the motherboard
battery for ten minute then install it again. It will clear the CMOS. Then reset
the CMOS/BIOS setup, date/ time etc. Another way to clear CMOS is, reset the CMOS
Jumper in motherboard.
To detect your hard drive you can try to check by change the hard drive cables. Change the port in motherboard. Check the BIOS setup and reset it if need.

The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased. Hope this helps
