Dell 4550 Sound Drivers For Mac
I have sucessfully installed Leopard on my Dell 4550 here are the specs: P4 3.06 ghz 1gig Ram ATI x300 (9500 PRO) Turtle Beach Santa Cruz audio card Intel 10/100 VE 20' dell flat panel 1 HD This is what I did. Installed JaS 10.4.8, (read directions on wiki) then installed the ethernet card on the Tiger OS: (thats the link, unzip it on another computer and place it on flash drive directions in are in the file) From there on I had the full installation done. (graphics are a little bad well work on that later) Then put in a patched ToH 10.5 disk in press on it on the desk top, install. When it asks for a reboot press yess. On the dell logo F12 then CD-Rom Drive, then F8, then -v. At the installer follow directions (do not reformat drives) and press on the HD you had tiger on.
Then from there continue, now just install X11, and System Files. 
Do not skip DISK TEST!!!! Wait a while when it reloads you have Leopard with working internet. Now you have to go and change the resolution.

Do this by going into /Library/Preferences/SystemConfiguration/ and open 'com.apple.Boot.plist' edit in Textedit. Right before the last line add: Graphics Mode WidthxHeightxColourDepth Replace the WidthxHeightxColourDepth with your settings. So if my setup was 1280x1024 at 32bit colour, I would add: 1280x1024x32 1) I could not save it into the system configuration folder so you need to save it as 'com.apple.BOOT.plist' on your desktop. DO NOT FORGET THE.plist ENDING! When saving you will have the option to save it as.plist or another format, choose.plist!
