booting issue on Dell Dimension 4700

[waif]

Hello there, I successfully installed OS10.5.5 on my Dell Dimension 4700 P4 3.0G 1G RAM, HDD: 1 SATA, 1 IDE , Ati Rdeon X300 Serial with 128 M. From the DVD installation I almost patched relevent files.

 

I could choose from BIOS to boot from IDE (only Mac partition bootable) or SATA (with WinXP loader using "tboot" at Boot.ini), either of options caused the same issue no mater to choose -v or -x; I have to power off to reboot.

Does anyone can help me to shoot the problem? Thank you all.
