Subject: [PATCH] /drivers/ide/pci/piix.c kernel 2.6.23
Date: Sun, 28 Oct 2007 10:35:06 +0000 [thread overview]
Message-ID: <80.104.88.232.880780238.1193567706@webmail.inet.it> (raw)
In piix.c (and in ata_piix.c) are already included some patches to skip the cable check on some laptops and to enable UDMA>33 modes, but I've noticed than theese doesn't work on my Acer Aspire 5602WLMi (maybe exist more versions of this laptop).
With this simple patch i can set transfert mode to UDMA100
