[PATCH RESEND] via82cxxx IDE: Add VT8251 ISA bridge

[PATCH RESEND] via82cxxx IDE: Add VT8251 ISA bridge

[Daniel Drake]

[-- Attachment #1: Type: text/plain, Size: 418 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.

Bart, I submitted this 2 weeks ago but sent it to your old pw.edu.pl address 
by accident. Sorry about that!

ACK.

VIA sent me the same patch, privately.
