If your pc (came with 80wire) it supports it
most people dont know what hardware they have. boards in the last ten years do support 4 hard drives with csl pin 28
It’s not the bios, its the controller that’s sees pin 28
To have solid DMA, DATA, CS
DMA switching off in windos after (6 CRC’s) get past the the fist stage of CRC protection
Multiple CRC retransmits between drive and controller, will cause this problem without faulting out.
The cause of excessive CRC’s
1 week single strength on you Ide controller or flaky
2 week single from optic or flaky
3 week motherboard or flaky
3 week IDE cable
If your DMA is off do not just turn it on or reset the controller driver, you need to fix the problem. optical drives are vary sensitive to smooth data flow.
The best fist step is to replace the IDE cable with a good EMI round cable.
Use Link Depot 18" ATA133 I have benched tested this cable and it flatout blows the high performace ATA133 80 wire ribbon away in speed and CRC reduction.
So if you have a week board or drive it can help make up the loss.
If you have good board and drive enjoy more speed and reliability.
