I installed JAS 10.5.4 on ASUS Pundit-R. It seems that IDE is not supported by Osx86. I have unsucessfully tried to install from IDE DVD on the internal IDE HHD and SATA HDD with several distributions (JAS,Leo,IAKTOS,Kalyway). I used a USB DVD and installed Leopard (JAS 10.5.4) on an external USB HDD as well. It worked at the firts time (I choose the kernel 9.2.0.). Then boot again from USB HHD. Everything is working except - Sound Card (i replaced by a sound blaster Audigy and installed the driver from driverheaven,it's still beta but you can use even 8 channels) - IDE HDD/DVD not recognized (I didn't try the SATA HDD). Hope this can help you.
