And one more install seems to have found the planets & stars in 
favorable alignment.  I got thru the install, networking is working 
(yaay) and yum -y update is now running.  And I didn't do anything 
different except take a pci card that acted like a dumb isa card back 
out of the system.  It was a triple 82C55 i/o card that had no bios 
rom on it whatsoever.  This card, while not being overly friendly to 
an lspci -vv listing, has never effected any of the previous installs 
or boot sequences.  Its been in that machine for about 6 months, but 
will not be used with the newer stepper drivers I just bought for 
emc's use.

This time it went thru the post install checks and let me setup the nv 
card & monitor pretty much to its full capabilities.  Sound worked 
even.  The acid test of course will be when I type 'switchdesk kde' 
and reboot after all the yum work is finished in a couple hours.  And 
hopefully no power failures as there is not a ups on that box, unlike 
these 2 here.  I'm up here on the eastern edge of whats left of 
Dennis & we've had intermittent showers since 3ish this afternoon.  
And it just started up again, this time having definitely found the 
instructions written on the heel.  Half an hour of this will equal an 
inch of precip.  The wind is gusty, to maybe 25 mph too. 

Wish me luck, I may need it...

This bios definitely does look at every disk in the system, but has no 
provisions to lock out hdb, so when that drive was made into hdb, it 
continued to boot from the first partition of that disk.  Weird, but 
thats the truth.  But after a few FC4 full installs, its finally 
booting from /dev/hda1, & once things settle, I need to go get the 
stuff in /dev/hdb1 and move it back so I can dual boot again.

Its a Mach motherboard, and its amazing.  The previous mobo that 
processor and ram lived in was a biostar, and the cpu never ran lower 
than 150F, and often closer to 170.  Same cpu & 266 fsb memory in 
this motherboard and the cpu, overclocked by the same 200 mhz, hasn't 
made it past 105 yet.  A huge Glaciator cooler on it, used to 1st 
degree my testing finger, now I can't tell for sure if its powered 
up!

I tried that, didn't make a spec of difference.

But it was showing me the /dev/hdb1/grub/grub.conf's contents in the 
grub menu, not /dev/hda1/grub/grub.conf's.  Now, finally, its 
straightened out again.  Till I put a spare 4gig drive in for swap 
(or possibly /var) that is. :-)  I detest having /var on the main 
drive in case it goes read-only & there goes your ability to 
troubleshoot by reading the logs cause there aren't any.  Been there, 
done that, tempted to buy the T-short even.

Didn't have to once the install actually worked, ifconfig now shows a 
normally configured eth0.

By turning off dhcp for eth0 and filling in the hostname and 
address/mask data yourself.  This small home network runs on the 
hosts file for address resolution till it hits the fireall box 
looking for an outside location.
