Hi, My computer has only primaly IDE but not secondaly. I connected a hard drive as Master and DVD-R as Slave on IDE. BIOS doesn't recognize IDE devices, but Windows XP that boots up from SATA hard drive can recognize DVD-R and can read files on the CentOS Installer Disk 1 of 4. Is it possible to start Centos4 Installer from WindowsXP? If possible, which file on Disk 1 should I click? Even if they are possible, can CentOS boot up from IDE Master hard drive? I think probably not. Thanks in advance, Takashi Nakamura
