What chips on my XMS4400C25?

.make sure you make a note of your settings in the Coms and then set them to standerd settings I.E 200 and auto before you flash the Bios, if this is overclocked at the time it could crash and you will have no Bios on your system so make sure you set everything to standerd setting in the cOms first before flashing.
It would be best to pull the battery and reset the coms, this way it will clear all the settings and put to standerd setting, when you have done this then flash the coms settings with the floppy disc, before you do this though make a not of what you have done with your settings so that you can start from where you left.
yes just put a formated floppy in the drive and the program will extract and install its self onto your floppy drive.
it is best to remove all power from the M/B take out the 240V plug, remove coms battery, and rest coms using jumper, then put jumper back to correct position, put battery back, then 240v power supply

Save bios along with flash program to disk. Think you need to add things like autoexec.bat, command.com etc too.
Best bet is to create a boot disk, and stick the rom and flash proggie on that.
This is why its LOADS easier to use windows.... Have probably flashed more bioses than you've had hot dinners and never once had an issue.. As long as you dont reboot if it says the flash failed your fine
<edit> Don't see why its necessary to go through all those lengths to clear cmos.. Just load optimised defaults in bios... Once you've flashed, do the same again, since there may be some settings "left over" from the old bios which wont work with the new one.... </edit>

Agreed - there is no need (under normal conditions).
For me I just drop the CPU back to 200mhz and volts on auto and all is well.
Well guy's i think there is something wrong...
I went to BIOS and used "Load Optimised Defaults" as Highland3r suggested after i tried to boot up PC, but dont know why it was crashing all the time with BSOD, then i reset CMOS with jumper, but PC was acting the same. I managed to boot it up a couple times in Window's but it crashed in a minute's time or so. Cant understand why PC should crash with default settings.
OK, after i flashed BIOS... Used update sacha suggested, everything went fine (i think). Looked in BIOS after flashing, but couldnt see any differnce??? Normaly some settings should change :?.
Then tried to boot up PC with default settings in "NEW" BIOS, but it was crashing again :? . WAF???
Then i changed settings for the ones i had before, couldn't get it boot with RAM @ 270MHz 2.5-3-3-8 2.92V, then i droped it back @ 250MHz 2.5-3-3-8 2.71V and booted into Window's with no probs.
Could anyone explain to me what a f**k is going on???

Sorry guy's my mistake :$.
I sorted out 270MHz, just forgot to set CPU multi, and it was on x10 so it's mean i was trying boot up with 2.7GHz @ 1.425V wich of course didn't worked. I droped multi to x7 and booted in Windows with RAM @ 270MHz 2.5-3-3-8 2.92V with no probs.
But still need to find out why it was crashing at stock speeds???

all memory is different you have got to get your head around this you can have the same make and model but one set could clock higher it all depends on the chips installed some can get better results than others, as your ram is rated at 275 with lose timings i don't think you will see those speeds with tight timings but you might get Lucky, the settings i have given you is a starting point, you may need to drop your volts again to see if this helps there are so many factors involved.
I would suggest starting from 250 again if it seems OK and just take it up a bit at a time.
anyway i have posted a pic of my settings and speeds i use, but do take into account my ram can run at 300MHz wheres yours can only run at 275 with lose timings.

I understand all you saying, of course every RAM will act different 8).
All i wanted to know is why my PC wasen't booting up with default settings??? Do you guy's have any idea about it?
Anyway... I did some tests with 270MHz
And look what i got:
CPU 1.89GHz HTT270 x7.0 1.425V
RAM 270GHz 2.5-3-3-8 2.92V 1:1
Over 4h no errors! :jumpwater
A quick SP2004 test:
Only now i found out from A64 screen that "Drive Strenght" was on "week", before it was on "normal" (probably did set it up by accident), does it make a big difference?
Look like BIOS update did a job, cheers guy's for it. And it wasn't too scary as i thought
.
Will see if i can get it work with 280MHz
Cheers
Edit: And 1M Super Pi was 1.500s faster as well.

Nice results, quite surprised how well a new bios has helped things! Weak drive seems to work really nicely for TCCD, that might well have aided stability wise too
Not yet Mate, i have something for dessert (will post it a bit later)
.
At the mo i have another strange PC behavior, after i cracked 280MHz i tried 290MHz and i droped multi from x7 to x6 to leave CPU out of question, but PC refused boot up??? I tried multi on x7 with 290 and it booted fine.
Whats wrong with multi on x6???
