I'm trying to install CentOS 5.5 on a couple of servers of type IBM System x3550 M3, but it's not going too well. Actually, the install setup phase runs as expected, and the actual installation also appears to be successful, but the system will not boot - I just get a message (presumably) from BIOS saying that boot from hard disk 0. If I start the installer again after this, or boot rescue mode off the install DVD, the installation is correctly found, however. Does anyone have any idea what may cause this and/or how I can fix the problem? Or is there at least anyone out there who has tried CentOS on the same type of hardware? Note that I've tried (re)installing several times, and also tested CentOS 5.4, but the result is always the same. I've also used CentOS without any problems on an x3550 M2, i.e. a slightly older variant of the hardware. I've (so far) installed with the default disk layout and package selection. - Toralf This e-mail, including any attachments and response string, may contain proprietary information which is confidential and may be legally privileged.
