ipodloader2 previously used 0x10 PIO mode. While faster, this could lead to data corruption with certain CF, SD, and SATA adapters..., causing the Invalid MBR error reported in #7. While commit f3bdd31 resolved most of these errors, porting ATA features from the Rockbox bootloader provides significantly better reliability across adapters.

This update also fixes a display controller bug where putting the Monochrome iPod into standby from ipodloader2 and waking it caused random vertical lines to appear due to an improper display shutdown sequence.

Tested on:

  • iPod 4th Gen Monochrome (128GB mSATA)
