Linux install problem on ICH4 chip On 845pe Mobo

[itchy]

I hav bought a new Gigabyte Mobo with intel 845pe chipset it has a ICH4 southbrige that control's the first 2 ide channels & promise raid 20276 chip runing as ATA not raid .My trouble is i tried to install Mandrake 9 and it didn't seem to register my ide chanels with my harddrive and cd rom the h/d is master on ide1 and cd-rom master on ide2 ,i have a burner installed on the promise ata chanelas master ,I have the bios set to boot A,CD on ide2 ,H/D on ide 1.When i put in the install cd in cd on ide2 it starts to load then stops with a mesage cannot read from cd/rw whitch is my promise ata chanel, So i put the boot cd in the cd/rw and continue install i start going through the setup then when it's time to set the mount point it cant find my Harddrives and asks what driver to load for scsi adapter .Ime not sure if i need a certain linux driver for the ICH4 chip to load as the scsi adapter ,there is a list of drivers to choose and i tried most of them ,then it asks what parameters to pass to the kernal.I am a newbe to linux and dont know where to go from here .i have no trouble instaling mandrake 8 or 9 on my other pc but its old and slow.Any sugestions ,Guides or links would help alot and be greatly appreciated thanks.P.S would i also need drivers for the AC97 sound Intel Pro/100 ve network adapter?
