I've managed to install CentOS 5.1 on S5000PAL with fakeraid Intel Embedded Raid Technology II Raid1 (LSI chipset) with some help of kickstart declaration 'driverdisk --source=http://.../driver.img' Then I've had some problems with yum update - new kernel didn't know about megasr.ko. I've solved it with commands: cd /lib/modules/ cp 2.6.18-53.el5PAE/updates/megasr.ko 2.6.18-53.1.14.el5PAE/updates/ depmod -a 2.6.18-53.1.14.el5PAE mkinitrd /boot/initrd-2.6.18-53.1.14.el5PAE-new.img 2.6.18-53.1.14.el5PAE at last I've edited grub.conf add '-new' to initr definition. I'm not sure why I need to do that twice, but it finally worked.: # uname -r 2.6.18-53.1.14.el5PAE Now I need to install Xen, so: # yum -y install xen kernel-xen After installation I've tried the same command sequence: cd /lib/modules/ cp 2.6.18-53.el5PAE/updates/megasr.ko 2.6.18-53.1.14.el5xen/updates/ depmod -a 2.6.18-53.1.14.el5xen mkinitrd /boot/initrd-2.6.18-53.1.14.el5xen-new.img 2.6.18-53.1.14.el5xen vi /etc/grub.conf (add -new, etc..) BUT xen kernel won'ts start. Kernel panic, 'unable to mount root', etc. Am I missing something? Is it possible to make it work? -- Tomek
