Question,,,,,,With 5 hard drives and all working semi-ok now ( 4 out of 5
restarts are fast, one takes forever)
Will clearing the cmos perhaps clear out perhaps some junk in the bios
(though i flashed the bios today)
i mean what advantages does clearing out a cmos have over loadingt bios
defaults?
Thanks to the experts here from whom i continue to learn from

Clearing the CMOS with the hardware jumper, clears all 256 bytes
of RAM inside the Southbridge.
"Load Setup Defaults" will at least re-write those bytes that
are used by the BIOS code. I cannot say for certain whether it
clears all bytes first or not.
Some DOS BIOS flashing programs have a number of options to be
used during the flash operation. One command line option is
to clear the CMOS, and presumably that clears the whole thing.
Clearing the CMOS with the jumper, should also reset the RTC
(real time clock). The RTC is in the Southbridge next to the RAM.
When you enter the BIOS setup screen, the clock should be
reset to some goofy value. That is handy, in fact, to check
whether the CMOS clearing procedure worked or not. I believe
I've had cases here, where after I thought I cleared the CMOS,
the clock in the BIOS still had the correct time. So I use that
as one test to see whether the CLRTC jumper has done its job
or not. When using the CLRTC jumper, always remember to unplug
the computer before using the jumper (that is usually stated
in the instructions in the manual, and is to prevent damage).
HTH,
Paul
