Can you elaborate how you tested this?
Here's what I was able to test on the ASUS A8N-E. The ports are numbered 1-4
on the PCB, not sure how that maps to your numbers above. I used a 40 GB
SATA disk with 'IDE_DISK_POLL_DELAY = 1' in FILO as well as the 5
seconds spin-up delay patch from the wiki.
- Port 1, 2 don't work.
- Port 3: Works (hde in FILO), I can boot from the SATA disk.
- Port 4: Works (hdg in FILO), I can boot from the SATA disk.
No change in behaviour with your patch applied. Ports 1/2 broken, 3/4 work.
