G5 Kernel Trap panic at startup after chime - Help!

Question

I have a Power Mac G5 2.0MHz Dual Core. The only externals are Mac keyboard, Mac mouse. No third party drivers installed since the HD is blank.
I can't even start up past the chime. After the chime, the screen gives me
unresolved kernel trap(cpu 0): 0x300
Kernel loadable modules in backtrace (with dependencies):
     com.apple.driver.AppleMacRISC4PE(1.6.0d9)@0x322c3000
          dependency: com.apple.iokit.IOPCIFamily(1.6)@0x322a5000
          dependency: com.apple.driver.IOPlatformFunction(1.7.0b1)@0x322b3000
I received this G5 a year ago. It was a working system, but the HD was pulled before I got it. I tried startup with Shift down. I tried startup with C-key down with bootable 10.4 CD.
I have put in a new Mac formated HD (no system installed yet) and reseated the RAM, but no luck. I cleaned the computer slots and reseated the monitor card.  I installed new RAM, zapping PRAM, cuda button, still no luck. I also tried putting RAM in 2nd slots in case the 1st slots were bad.
Upon startup holding Shift key I get this on screen:
panic(cpu 0 caller 0x002DE020): Unable to find driver for this platform: "PowerMac11,2"
Does this mean a processor or logic board is bad? What are my options? If it is chiming at startup, would the hair dryer trick even be worth trying?
Help!

Answer 1

I don't have the disc here. Do you suppose 10.4.0 will not run on it if 10.4.2 will?
Absolutely, & 10.4.2 is a gray Machine specific Disc, Retail 10.4 Discs were 10.4.0, 10.4.3, & 10.4.6 as I recall.
10.5 Retail Disc should work also for any G5.
