: : : Hello,

: : : I have a HP Pavilion 8370 which has an ASUS P2B98-XV MOBO and a Pentium II 350MHZ. I just installed 256Mb of ram(single stick) and although it seems to work fine, my Phoenix BIOS reports 0Mb of ram installed. I decided to update the BIOS from ASUS's newest BIOS designed specifically for the ASUS P2B98-XV. Went ahead and flashed it, cleared the CMOS and now everytime I boot it displays PII 175MHZ and then proceeds into the SETUP Utility, and goes to the section containing the Core CPU Frequency settings while a blinking message at the top of the screen reads-

: : : 'Computer not properly shut down or CMOS Checksum Error. Check CPU Core Frequency'

: : : Now according to my ASUS manual, that particular setting is not used as I have jumpers on my MOBO for setting the Multiplier and BUS speed. I tried all combinations but the computer would keep doing the same thing.

: : : I have an EPROM burner and went ahead and report any problems with the CMOS and I checked reflashed my Phoenix which by the way doesn't the Battery voltage and it reads 3.0V.

: : : Am I simply stuck with this crappy Phoenix BIOS? I sure would like to use the 256MB single sticks as ASUS states that my MOBO can support 768MB total. HP states in their manual it can only handle 128Mb per slot.

: : : Can I use another BIOS possibly? Maybe P2B drivers? I have no clue as to what to do here and the computer is already 3 years old so I am looking to get the most out of it while I can.

: : I'm afraid that you are stuck with the BIOS; you are not likely to find a board with the same chips using a different BIOS - BUT if you do it would be worth trying (BE SURE AND SAVE your old BIOS BEFORE you kill what you have) consider flashing a new BIOS chip so you can recover quickly.

: : Memory usage/recognition is usually a chipset function, NOT a BIOS function. In addition to voltage (3.3, 5.0) and frequency (66, 100, 133, ...) chipset limits include total onboard MBytes, Maximum MBytes per stick and Maximum Mbits per chip on the stick. Older boards are more likely to recognize all of the memory if the sticks have chips on both sides (lower bit density). I'd be inclined to believe HP's maximum MBytes/DIMM; ASUS may have made the boards per HP requirements, used an earlier version of the chipset or ... Can you try some 128MB DIMMs?

: : Good Luck,
: : Henry

: Thank you for responding so quickly. I do have a 128Mb stick but it is ECC which they don't sell anymore(maybe on EBay used) and while memory is nice and cheap, I am looking at the fact that total memory would be reduced to a paltry 384Mb.

: I guess I'm not quite sure why this memory doesn't show up in BIOS but does come up on the Memory test when I start the machine and does show up in Windows. I haven't had any crashes. The only thing I have noticed is that some programs seem to take longer to start which I think may be due to less disk caching per more memory.

: I don't know if this board is modified but as you mention it may have been which may be the reason why the BIOS has that weird CPU Core frequency message. Do you know what that is all about?

: I seriously don't want to keep this computer if I can't do anything with the BIOS as I originally bought this computer with little knowledge of computer hardware and now that I know, I want to tweak this old machine a bit.


I have no clue what the CPU messages are about - I'd consider going back to your original BIOS or an intermediate one.

As you load a PC with RAM, other limits get in the way - check the chipset spec sheet (a book) for the amount of ram it can cache. Another limit is windows - the later versions and NT type OS can use memory pretty well, but there is a practical limit where performance doesn't improve with added memory and sometimes deteriorates. My win98 system does a VERY POOR job of releasing memory after an app is done; I have a ram monitor that I use to force memory release when I think the system may be approaching a trouble zone. Techs have told me that win98 can only use about 512MB effectively (but I KNOW thsat win98 will run fine with 1GB RAM).

Good Luck with the BIOS.
Henry
