Same here. I don't think the board is ATA-66 capable. I bought it about
1.5 years ago and the manual tells just something about UDMA-33.
Is there some code missing? In alim15x3.c I can see:
static byte cable_80_pin[2] = { 0, 0 };
...
unsigned int __init ata66_ali15x3 (ide_hwif_t *hwif)
...
if (m5229_revision >= 0xC2) {
...
if (!(tmpbyte & 0x01)) cable_80_pin[0] = 1;
...
But cable_80_pin is static and not read anywhere. m5229_revision is
most likely 0xC1 and thus cable_80_pin[0] should be 0 anyway. At the
end of that function is another cable detection that is unconditional:
pci_read_config_byte(dev, 0x4a, &tmpbyte);
ata66 = (!(tmpbyte & ata66mask)) ? 1 : 0;
If ata66 is not supported at all, the appropriate bits may default to
0, which would be misinterpreted.
