I have installed CentOS 4 on LSI Megaraid 467 (I believe what Dell would call the Perc-2/DC - AND it has booted and is running. Much thanks to Tom Sightler for his excellent blog. I have included a copy of this in the event it helps him to adjust his blog. For completeness, his blog is here... http://www.tuxyturvy.com/blog/index.php?/archives/4-Installing-RHEL4-on- Systems-with-Legacy-Megaraid-Drivers.html Adjustments MUST be made to accomplish this on CentOS - the reason is that CentOS permits 586 hardware and thus the installer reduces the lowest common denominator and you have to use the 586 version of the kernel to use anaconda but then you need the 686 version for first boot. The file you copy to your installed base in /lib/modules/2.6.9-11.EL/kernel/drivers/scsi/megaraid should be the 686 version, NOT the 586 version necessary for the anaconda installer. Thus the way I got it done... mkdir /usr/src/software cd /usr/src/software wget http://www.tuxyturvy.com/files/megaraid2.tar.bz2 yum install kernel-devel-2.6.9-11.EL.i586 mkdir /usr/src/megaraid cd /usr/src/megaraid tar jxvfp /usr/src/sofware/megaraid2.tar.bz2 make -C /lib/modules/2.6.9-11.EL/build SUBDIRS=/usr/src/megaraid modules then copied megaraid.ko to a floppy and labeled it megaraid-586 then I cleaned out the kernel-devel...to make way for the 686 version rpm -e kernel-devel yum install kernel-devel then cd ../ mv megaraid megaraid-586 mkdir megaraid cd megaraid tar jxvfp /usr/src/sofware/megaraid2.tar.bz2 make -C /lib/modules/2.6.9-11.EL/build SUBDIRS=/usr/src/megaraid modules then copied megaraid.ko to a floppy and labeled it megaraid-686 You could probably repeat for smp kernel if you have multiple processors now...you should be getting the pattern except that you can have kernel- devel and kernel-smp-devel installed at the same time. You cannot have kernel-devel for both 586 and 686 'uni-processor' both installed at the same time. Anyway, the 586 is used during installs or 'linux rescue' efforts when you screw up ;-) I found that when I booted into linux rescue, I could switch consoles.. Alt-F2 rmmod megaraid_mbox rmmod megaraid_mm mkdir /mnt/floppy mount /dev/fdo /mnt/floppy insmod /mnt/floppy/megaraid.ko and be working... this process may be easier than 'noprobe' option passed at boot Craig
