This is what I got. My question follows.

Thanks.

Note that this is actually a LGSemi part, which I guess is now listed under
Hundai since the merger a few years ago... and LG did not stand for "Life
is Good" back then:-)... but Lucky Goldstar.

Does your BIOS Setup not have Auto settings to use the SPD info? If it
does it would be a good idea to see what it makes of it first before
fiddling with things. If you have no other way to find out current
timings, memtest86+ (www.memtest.org) usually shows it for chipsets I've
used.

Maybe you're confused because you have a DIMM capable of PC-133 operation
but you're running it at 100MHz? Based on the info shown above I'd try
Tcl=2, Trcd=3, Trp=3 & Tras=5 and run some tests to see if it's stable; tCL
at 2 *might* be pushing it a bit, especially with more than one DIMM in the
system

I believe those are PCI Bus settings and you can safely turn both on unless
maybe you have an old PCI card.

>On-chip Video Windows size : 64MB, off

If you don't have a separate video card, leave this at 64MB, otherwise set
to zero. If you have 256MB total memory with just that one DIMM and don't
do anything which needs the extra video memory, you can likely get by by
setting it to 32MB.

This just dithers the system clock, supposedly for RFI reasons. I always
turn it off, figuring I'll enable it if I need it.
