Dualbooting on 2 hard drives

[viiComm]

I have an Asus p5b-vm motherboard with a 2.8Ghz Core2Duo processor with a sata and an ide winchester.
I have ideneb 1.6 installed on both winchester but cannot resolve the multibooting problem.
I downloaded the Chameleon RC2 and installed as the readme described. I made on both winchester anyway.
After restart, independently which winchester was the first in the boot order of the Bios, no gui appeared however the systems have been set up.

I tried to make a com.apple.Boot.plist into the folder of /Extra with this content:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Kernel Flags</key>
<string>rd=disk0s2</string>
<key>Timeout</key>
<string>5</string>
<key>Boot Graphics</key>
<string>Yes</string>
<key>Instant Menu</key>
<string>Yes</string>
<key>GUI</key>
<string>Yes</string>
<key>device-properties</key>
<string></string>
</dict>
</plist>

But the result is the same. No GUI, no system choosing option. Would you be so kind to help me how to achieve multibooting?
