Update existing drivers instead of slipstreaming drivers?

[BalusC]

I have an old IBM PC Server 704 with Quad Pentuim Pro 200 standing here. This server has two integrated Adaptec AIC78xx controllers, each connected to one 6-connector SCA backplane. When installing W2K Server, the setup will hang during the format step. The format of a disk connected to the SCA backplane could never be completed. W2K3 works, but after all it sees only one CPU of the four (KB 319091), so this is really no option.

After research I found out that the Adaptec AIC78xx.sys driver need to be updated in order to recognize and work with the SCA backplanes correctly. So I created a driverfloppy with the most recent drivers, which I can use during the F6-step of the setup. But W2K setup seems to ignore those drivers and stuck on using the integrated (and older) drivers. Resulting in a hang during the format again.

Well, the next step was to change the drivers manually and create a new setup CD. So I changed the old \i386\AIC78XX.SY_ file by the new version and burned a new setup CD. This worked, the setup completes the format and will continue all the way until the finish. After finishing the setup, the first fresh boot will hang. I decided to move the harddisk to my PC and I noted that the aic78xx.sys driver in \winnt\system32\drivers\ is still the old version. After replacing manually by the new aic78xx.sys driver from the driverfloppy and moving the harddisk back to the server, Windows will boot successfully.

OK, this worked, but it would be nice to having a setup CD ready for the future which installs the OS, without any extra rework like swapping disks. So I investigated the setup CD and found another AIC78XX.SYS file in the driver.cab. It seems that this old version from the driver.cab has replaced the new one from \i386\ during the (end of?) setup.

I have found many articles about slipstreaming new drivers to create an unattended setup CD, but I haven't seen an article yet about simply replacing a driver in driver.cab by a newer version, keeping the same filename.

Any information or tips?

No ideas yet?

Summarized: all I need to know is how to rebuild the driver.cab after replacing an existing driver by a newer version.
