I just download Xen source and do "make world;make install;depmod..;mkinitrd...". I don't know which config file will be used if I build Xen like this (maybe the config-2.6.16.29-xen under the directory dist/install/boot).

I did a grep with "CONFIG_BLK_DEV_PIIX" and found it it set to m in the config-2.6.16.29-xen. I did a modprobe piix, however my CD-ROM is still not fired up (nothing is show up /dev/ as either cdrom or hd*).

Hi Tim, Keir and Mats,

I attached all the detailed log files (text file format). The file extension
indicate the version of environment. Please take a look.

ESB2 should be supported by the piix IDE driver. Which XenLinux kernel
config are you using? Either you need the driver compiled into the kernel,
or you need to load it as a module. Look for a line containing
CONFIG_BLK_DEV_PIIX in your .config -- it should be "=m" or "=y".

If it's compiled as a module, and you installed the modules on your
filesystem, you may be able to fire up the CDROM drive by typing 'modprobe
piix'.
