Hacking is easy........Doing it correct is pain.
It is obvious that you have blown off the patches.
For the record, us how you managed to signal the card to invoke ATA-66?
I had to get Promise to help me, oh they asked to use the 2.3/2.4 chipset
code for a module load. Since ther kernel must know if the host adapter
has detected the 80c ribbon and verify that that the device/drive had
registered the presense also, before if can verify that transfer rates are
stable (no lock up or FS "root-wadding" == trashed data). If the drive
fails to invoke any Ultra DMA modes because of anything, you are required
to perform a HARD rest to the drive and controller to get it to generic
DMAing.
The warning and disk death could go on for ever..........but doing what
you just did and advised people to do is "FOOLISH"........
So if anyone out there does follow the ill-advise below, don't ask for
help.........I will not care and will not take the time to offer a
recovery kludge.
Did you purchase that extended warrenty for drive replacement?
