PCI-Express to SATA II ...updating :-)

Asus M3N78 (plain one ...i.e. not a [M3N78-??]
x6000 Windsor
2x1gb Crucial Ballistix ...(that will now only run at normal timings and
voltage, but, that's a whole different story!)
XP Home ed. SP3+ subsequent updates.

....a little while ago I fitted a Silcon Image SIL 3132 PCI-Express to SATAII
card, (in order to add in a 3rd SATA II hd). ...not using RAID btw.
....and I've been wading through the downloads and related "read-me's" for
updating it's flash bios, mainly out of interest but, now I notice a slight
driver/bios version mismatch.
http://www.siliconimage.com/products...ct.aspx?pid=32

I currently have versions / 7.3.1.3 bios on the card and 1.5.19.0 driver
installed into Windows.
...yet the description for driver 1.5.19.0
http://www.siliconimage.com/support/...x?pid=32&cat=3
suggests that I should be using bios 7.5.0.7 with that driver, which
appears to be newer than the bios currently on the card i.e - 7.3.1.3

....before someone says "If it ain't broke don't fix it," ...I was just
having a rummage around, and collecting up the relevant (newer) bios, flash
updater etc. and selecting the relevant files gets more difficult the more I
read !

i.e. I've obviously got to avoid the bios files for motherboard tweakers
that want to add SIL3132 code into a motherboard bios, and also avoid the
"base" version ? ... meaning I think the bios file I want is prefixed with
an "r"
....and I eventaully spotted that the Windows flash updater requires Sun
JAVA, which I will not allow into my machine ! ..I think ..even though one
would be using a Windows DOS box ?
....perhaps I should do it in DOS ? ...hang on, ..no floppy drive !!

....other considerations a-
I do not use RAID, ... and when I first installed the card, (using its'
supplied CD), it was a "hit and miss" affair in that one had to sort of
choose RAID, in order to get the driver installed so that I could use 1 SATA
II hd connected to it, for use as a non-raid disk :-(

....anyhow, do you think that flashing the card with bios version 7.5.0.7 is
wise ?

....also Device Manager | SCSI and RAID controllers | Device Info tab ...says
"Host Link Speed" & "Device Link Speed" are both "Generation 1 (1.5Gb/s)",
though I think I spotted in a discussion forum a couple of months ago, that
this was simply a labelling error, and that hd benchmarking utility would
disprove this. ...will Lavalys trial, hd benchmark gimme a reading, ..it
will not!

....anyhooooo, any tips muchly appreciated.

regards, Richard.
