i have a chip via82c686a (Epox 7-kxa)
at boot time is been detected via82c686a
proc says via82c586b
lspci -vvv no says
the udma capabilities is not work propetly i set manually with "hdparm -m 8 -W 1 -X udma5 /dev/hda" whats happening here?

The drive doesn't say to the OS which DMA mode is enabled on it.

Because all VIA IDE chips say they're 586b.

Quoted 1 line

The chip doesn't support UDMA5. The highest speed it supports is UDMA3 (UDMA66).

Quoted 1 line

whats happening here?

Nothing unusual.
