Yes, that was part of the patch. It turns out that the "do_mounts.c" part is not necessary for the RH 7.2 kernels, as it is already there for the more recent DAC960 controllers that come with firmware that the Linux driver supports. > I hacked a custom RH7.2 CD where i pulled apart the CD > pulled apart the initial ram disks searched for any instance of DAC960.o > and modified the string 2.73 to 2.70 in the module. YES!!! Great tip - saves the hassle of having to rebuild! I was able to use "emacs" to binary patch the DAC960.o module; just search for "2.73" and replace with "2.70" (don't include the quotes). Save it and it'll "just work" - thank goodness there's no checksum... ;-} > I then reassembled the CD and made a new ISO. > > It booted OK found the controller and installed OK. > The only problem was RH installed a different DAC960.o file from > a kernel rpm that i didn't patch and left the system un bootable (root raid) Yup, there's always one that gets away... ;-} > I had a another copy of RH7.2 on another disk so I was able to mount the > raid partition and install a patched kernel with a modified DAC960 driver > built into the kernel > > If your interested I can send you the relevant bits from my custom CD > > Also see my posts on the debian-alpha-list Thanks for the extensive feedback and help, Rick. Needless to say, it's a difficult task to rebuild the install CD. We are currently working on a new ISO set for RH 7.2, including all the update RPMS, along with a new set of kernel RPMS based on 2.4.18. These have been tested in a root-on DAC960 configuration, and worked well. But PLEASE, don't ask when they'll become available, we have a lot of testing still to go through. In the meantime, via judicious use of binary editing, mkinitrd, and such, one can convert a non-DAC960-rooted installation into one that is. Good luck, and feel free to ask more questions on how to do this... --Jay++ ----------------------------------------------------------------------------- Jay A Estabrook HPTC - LINUX support Hewlett-Packard Company - MRO1-2/K15 (508) 467-2080 200 Forest Street, Marlboro MA 01752 [EMAIL PROTECTED] -----------------------------------------------------------------------------
