Subject: [PATCH] via82cxxx IDE: Add VT8251 ISA bridge
Date: Tue, 22 Nov 2005 22:34:49 +0000 [thread overview]
Message-ID: <43839D09.40306@gentoo.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 306 bytes --]
Some motherboards (such as the Asus P5V800-MX) ship a
PCI_DEVICE_ID_VIA_82C586_1 IDE controller alongside a VT8251 southbridge.
This southbridge is currently unrecognised in the via82cxxx IDE driver,
preventing those users from getting DMA access to disks.
