need help with some os x 10.4 cd backups

[pcchris]

i have 4 os x 10.4 cd dmg's that wont boot when i burn them and i have an ibook to play with for 2 months with only a cdrom

 

ive converted the dmg with ultraiso and burned and even burned with transmac tried dmg2iso it didnt put out a proper iso (size was 3mb)

 

anone know some software or a way that would work without a mac with a burner

 

i wish i could install os x from the harddrive or via network from my windows pc

 

i need a better way then buying and external drive

 

plus do you all think it would install my ibook says 500mhz and 192mb of ram im praying that 64mb extra of it is being used as a Vram
