8iPE775-G problem, need help

The manual for this board documents a setting in
BIOS where I can set the memory speed multiplier as
follows:
main menufrequency/voltage control"memory Frequency for"

manual shows 4 settings for FSB = 800 Mhz: 2.0, 1.6, 1.33, auto

But when I go into BIOS it shows only 2.0 and auto. I must run my memory at
1.6 or 1.33. How can I see the choices the manual shows?
How can I force the mobo to run at 4:5 memory to FSB
ratio?

Second problem: My BIOS is "F4", date of Feb. 2005.
The gigabyte site shows the latest as "F3" with a
Sep. 2004 date. I D/L F3, but it won't load, I get
an error message and the update stops. How do I
flash the BIOS (I mean besides the normal way which doesn't work)
Anyone else successful at doing this?

fwiw, I run a pair of GA-8iPE775G with 533MHz FSB cpus with F4 bios. I
use DDR333 memory.

I am presented with 2.0 (for DDR266), 2.5 (for DDR333), Auto options.


So it would appear Gigabyte have perhaps withdrawn support for slower
DDR266 and DDR333 memory with the F4 bios if one plans to use 800MHz
FSB cpu.
