Part 2: Overview of “Lost CMOS”
Q: What is the “Lost CMOS” problem?
A: The motherboard will show an error message on boot-up that says something
like “CMOS battery low, CMOS settings lost, Press F1 or F2…” This is normal
after using the “Clear CMOS” jumper, but shouldn’t happen spontaneously. On
motherboards with this “problem” the CMOS settings will be lost repeatedly,
apparently without cause. The frequency of loss varies from once every few
weeks to every day, depending on the board.
Q: What is the cause of the “Lost CMOS” problem?
A: The cause is not known, but it appears to be fixed when the Memory
mis-detection/CONFIGMG error is fixed as shown in the next part of this FAQ.
PART 3: The (best-known) “solutions”
Q: What can I do to fix this problem?
A: There are several options:
1) Apply the “R182 fix.” (See here for details)
2) PC133 memory always seems to be detected correctly. Try using PC133
instead of DDR memory.
3) Use 128MB DDR memory modules with only 8 chips. These sometimes are
detected correctly on problem boards. The more common 256MB or 512MB DDR
modules with 16 chips make the problem show.
4) Exchange your motherboard. The author’s testing indicates that only a few
percent of motherboards are effected by this problem, so an exchange is
likely to provide a complete solution.
5) Turn off ACPI. This is not recommended, but does mask the problem enough
to allow Windows to boot in many situations. (It is not know if this also
works around the “Lost CMOS” problem as well.)
6) Some boards only have the problem when the SiS 735 chip is cool. Turn
your computer on and wait for a few minutes in the BIOS screen. Then exit
the BIOS and let it finish booting. This will allow the SiS735 to warm up.
(You may still suffer from “Lost CMOS” with this work-around.)
PART 4: Summary of testing and research
Test Setup:
Various BIOS versions, up to and including 011215s.rom
AMD Approved Power Supplies from several brands, 300 and 350W
PC2100 DDR memory
4 boards with sticker marked “6” near the PCI slots, all known to have the
problem.
Test Results:
So far, about 10 boards with the Memory mis-detection/CONFIGMG problem have
been 100% corrected with the “R182 Fix”
Of those boards, two were observed to have the “Lost CMOS” problem
frequently. These have almost never lost their CMOS settings since the “R182
Fix” was applied.
In an effort to isolate the problem, 3 boards had the 735 heatsink removed
and were attached to a temperature controlled aluminum block that was placed
on the 735 chip with thermal compound between the two. The motherboards were
rebooted many times at different temperatures on the 735 chip. It was found
that the problem happened over a range of temperatures, different for each
board, but all in the 15-40C range.

L'ho letta gg fà, su suddetta FAQ manca la sezione con le modifike HW
presenti nel sito da me lincate...
Oltre ke altre cose, presempio come creare un floppy d'avvio sotto WinXP/2K
cosa molto + semplice ;-))
Cqm complimenti ad Aragorn per tutto il resto....
Ciao

 Cqm complimenti ad Aragorn per tutto il resto....
Le faq non sono aggiornate (o meglio lo sono ma non sono state ancora
rilasciate al pubblico)...molte delle cose scritte sono gia' state inserite.
Il sito francese e' molto molto indietro...(vedi la faq relativa alla
revisione della scheda....)
