Slow Disk Operations in BootIt NG

Assuming the drive itself is not slow, this problem is usually caused by the system BIOS. You can try to correct this issue as follows:

  • Some BIOS brands and versions will not automatically detect the mode properly, so you can try setting the PIO mode in the BIOS as appropriate (and nowadays, mode 4 would be your choice).

  • Some BIOS brands and versions support UDMA directly. If such a setting is available in your BIOS, try enabling it.

  • Ensure that you are using an 80-conductor IDE cable, where applicable.

  • Consider using the third-party DOS UDMA Driver available here, with the understanding that it is not officially supported and is to be used at your own risk.
