I am running CentOS 4.7, presently on an older box (PIII slot 1 processor @ 500mhz with 384meg of RAM, using SCSI disks with an AHA-2940 host controller). I have built a new box: AMH Semporon 2.<mumble> GHZ, 2gig of RAM. I put in a AHA-29160 host controller (uses same driver as the AHA-2940). The motherboard is an ASROCK thing with nVideo's chipset: nv's SATA controller and nv's integrated network (forcedeth). I just did some tests with live CD and installer CDs for CentOS 4 and 5. It looks like the stock CentOS 4 kernel's achi and forcedth drivers don't really care for this board :-(. I bought a SATA DVD burner for this system -- it looks like I won't be able to use it unless/until I upgrade either the kernel or the whole O/S (eg to at least CentOS 5.3). I really don't want to go an upgrade to CentOS 5 at this time. Do I have any other options? I have the kernel-devel installed -- is it possible to 'steal' the sources for later kernel drivers and re-compile them for the kernel I am running? Are there other options available?
