[Bug 36664] Installer should configure /etc/hdparm.conf

[Luna-Tick]

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Every time that I re-install ubuntu, I reconfigure my hdparm.conf file.
I am really happy to see that, in Dapper, DMA is turned on for my hard-
disk and CD-Rom without my having to edit the files, but there are other
options that are not set up for me.

I was told that my machine could handle, and should therefore turn on,
the following:

/dev/hdc {
	dma = on		   
	io32_support = 3
}

/dev/hda {
	mult_sect_io = 16
	dma = on
	io32_support = 3
}

The DMA seems to be on now by default, but the other options are on the
lowest setting. Is there a way of going through the hdparm options,
testing if the machine can handle them and turning them on if it can? I
have no doubt there are many other options in hdparm that I should have
on but that I don't understand.
