Subject: hdregs.h puts csfo at word 129 - wrong, that's vendor specific
Date: Thu, 24 Mar 2005 17:28:31 -0800	[thread overview]
Message-ID: <4243693F.9090008@yahoo.com> (raw)

ide-disk.c checks csfo bit 0 to see if the cache is available on a device
hdregs.h maps csfo to word 129 of the Identify Device information
the latest ATA documentation, e00159r3 Mandatory IDENTIFY DEVICE 
information, says words 129-159 are Vendor specific.

Why is the driver switching on cache operations based on a word that has 
nothing to do with cache?

My previous attempt was obviously too long?

Chris
