What I typically use, is 7ZIP to burrow inside. This is the folder
path, to the driver files for an SB700 Southbridge. Five files.
$_OUTDIR\Packages\Drivers\SBDrv\SB7xx\RAID\W764A\

It appears the driver at install time, is an AHCI based one, used
to bootstrap the RAID process. That's all I can guess by looking at
those files.
You could try putting that directory of five files, on a storage device.
A floppy, or a USB stick perhaps. Then, start the install, and see if
there's an option to offer that driver set. Note that the set I
picked there, has no "TXTSETUP.oem" which would have been for another
OS.
By comparison, if I download the WinXP version (92MB), there's a folder
in there like this. Actually, some of the look-alike folders, don't
have a txtsetup.oem, so in fact the folders are not uniform in design.
I'm only offering this as an example, to show WinXP could be slightly
different.

Anyway, extract the
$_OUTDIR\Packages\Drivers\SBDrv\SB7xx\RAID\W764A\
folder, and put the five files where Windows 7 can find them. At
least the Localizable Strings description looks promising.
Best guess,
Paul
