Previously (many years ago) I had to do the same thing with Slackware since I did not have an optical drive then. The process is like this: - Make a FAT partition - Copy all the installation files (all disks) to the FAT partition - You'll need a Kernel, a INITRD image and LOADLIN program -- Kernel and INITRD is in cd:/images/pxeboot -- You can find loadlin from the web - Boot DOS (probably via a floppy) - Use loadlin.exe to boot the linux kernel If I remember correctly the command line was like this: C:> LOADLIN.EXE VMLINUZ load_ramdisk=1 initrd=initrd.img RO But please check the loadlin documentation. I have not done this for years and I am not sure if it works with CentOS. -- sukru Takashi Nakamura wrote: >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?
