I am wondering if anyone has encountered a situation similar to the following. I have a MSI-NEO2-LS board with ICH5 sata controller. In the bios, I set the SATA mode to "Native" and "SATA only". So, the IDE layout of my machine looks like: IDE1 Master: 20G Samsum IDE disk. IDE1 Slave : a ZIP 100M drive IDE2 Master: RIcho CDRW IDE2 Slave: LG DVD IDE3 Master: 80G Seagate ATA disk (ST800??) .. I first booted the FC1 installation disk1 from the RICHO CDRW. The installation process stoped ,after "Media test", on a just blank blue screen with three buttons on the bottom. (before "run Anaconda..", I guess.) The system did not lock up as after "ctrl+alt+del" it can print out "send terminal signal..." and reboot the machine. I found when it happened the light of my RICHO cdrw was always on. I suspect the ata driver treats the CDROM as the sata disk by mistake, and tries to do something on it(Do not believe in me anyway.). So, I put the FC1 disk1 into the LG DVD, and boot from it. This time the installation goes fine, and it recogonizes both of my hard disks (IDE+SATA). (I can see both of them when I manually allocate partition for Linux.) I guess there must be a bug somewhere, but not sure if it is in the sata driver or FC1. cheers, Dan Try swapping which cd / DVD drive is the master and slave. I have a DVD and DVD read/write and my system is only happy if the read/write drive is the master. Regards roger
