There Is An Error On The Bois Update V1.9

Question

hi all
i have a pentium 4 { (2.4) (FSB 533 )} processor on a ( 875P NEO FIS2R) motherboard with 512MB of RAM (DDR 333) ( kingston ) in my computer .
newly i have an experience in flashing my BIOS ( VER 1.2 ) to (VER 1.9)
then evrtings was running good .
but whenever ( corecenter ) program was running , an error was showing
in (win98se) and system was restarting in win2k and also in winXP. and
when systems was booting i had 3 restarts on computer and then system
was booting up.  
so i reprogrammed my BIOS to old version and now everytings are running
good and corecenter is running right.  
i dont recommend flashing to (ver 1.9) for this motherboard.
{if you want to use (corcenter)}.
but you can try other versions like (VER 1.8).
good luck.

Doesnt seem to work the same flashing backwards tho ...I had a lot of instability with 1.9 including boot failure and losing ALL the bios settings several times
I flashed back to BIOS 1.5, enables PAT and has a nice performance increase over previous versions but doesnt (didnt?) have MSI's performance modes (MAT Slow/Fast/Turbo/Ultra-Turbo ...introduced with 1.6). I didnt want MAT because in order to activate Intels PAT (Performance Acceleration Technology -the reason for buying an 875 board) you have to run at Fast or above which also overclocks the PCI/AGP and graphics card clocks
...anyway the strange thing is my 1.5 BIOS now has the performance modes (MAT) included which it didnt the first time (flashing up through the different versions as they were released)  
875P BIOS changes
1.0 (14/April/2003)
This is AMI BIOS release
1.1 (28/April/2003)
-Adds multi-color warning on the BIOS setup
1.2 (29/April/2003)
-Updates CPU Microcode
1.3 (?)
KILLER BIOS -removed
1.4 (22/May/2003)
-Modifies CPU temperature detection CPU reading reduced by about 7-10C
-Fixes system unstable with some DDR400 memory
-Fixes some system cannot overclock
-Modifies bug in multi-language
Default DDR voltage lowered to 2.5v -some systems become non-bootable after flashing
Bad flashing program -users restart before the program has really finished =DEAD board
1.5 (18/June/2003)
-Modifies BIOS so it does not Auto-Disable onboard sound when PCI sound card is installed
-Fixes some DDR400 memory compatibility issue
PAT enabled (atleast for 1:1 ratio) -big performance increase over previous BIOS's
New flashing program included in BIOS download
1.6 (26/June/2003)
-Support MAT function
Performance modes introduced
PAT is only available in FAST mode and above -which overclock the AGP/PCI/chipset and graphics card clocks
^^^MAT Introduced with 1.6 ...so why is it still there when I flash back to 1.5?
Edit red/green comments are my observations from when the BIOS was first released
