 ===== I am unable to update/flash my BIOS, why? =====
-Please check jumper on JP4 first. If no jumper is installed, please add a jumper cap onto pin2 and pin3. If a jumper installed on pin1 and pin2, please remove it and install onto pin2 and pin3.

-===== Why is "CPU Clock" under Frequency/Voltage Control in the CMOS Setup Utility can only go up to 132MHz, not as manual mentioned as 165MHz? =====
+===== Why does the "CPU Clock" under Frequency/Voltage Control in the CMOS Setup Utility only go up to 132 MHz and not to 165 MHz as mentioned in the manual? =====
-If FSB 100MHz(400MHz) CPU is installed, the CPU Clock range is from 100MHz to 132MHz. If FSB 133MHz(533MHz) CPU is installed, the CPU Clock range is from 133MHz to 165MHz.
+If a 400 MHz CPU with a 100 MHz FSB is installed, the CPU clock ranges from 100 MHz to 132 MHz. If a 533 MHz CPU with an FSB of 133 MHz is installed, the CPU clock ranges from 133 MHz to 165 MHz.
+===== How can I run my DDR-333 (PC2700) memory module at 333 MHz while using an Intel CPU with an FSB of 100 MHz? =====
-===== How can I run my DDR333 (PC2700) memory module at 333MHz while using Intel CPU with FSB 100 (400) MHz? =====
+According to Intel's chipset specifications, it is:
-According to Intel chipset specification,
+  - FSB 400 MHz and DDR-200 supported.
-  - FSB 400 MHz and DDR 200 supported.
+  - FSB 400/533 MHz and DDR-266 supported.
-  - FSB 400/533 MHz and DDR 266 supported.
+  - FSB 533 MHz and DDR-333 supported.
-  - FSB 533 MHz and DDR 333 supported.
+As standard guidelines:
-and standard design guide:
+  - When using a CPU with an FSB 100(400) MHz, DDR can only run DDR333 (PC2700) at 266 MHz.
-  - When using CPU with FSB 100(400) MHz, DDR can only run DDR333(PC2700) at 266MHz.
+  - When using a CPU with and FSB 133(533) MHz, DDR-333 (PC2700) can run at both 266 MHz and 333 MHz.
-  - When using CPU with FSB 133(533) MHz, DDR333(PC2700) can run both 266MHz and 333MHz.
