Set UDMA mode to speed up Ghost system recovery speed

Many friends like to use Ghost for system backup and restore, but sometimes when you use Ghost (DOS version) to recover the system, you will find that the speed is very slow, the display takes half an hour, and the previous backup and recovery The system only takes a few minutes.

Is it because of the "high" mode selected when backing up with Ghost? So I tried to use Ghost to back up the system. It took 40 minutes to see the time display. It was slower than installing a new system and scared myself. Checking the hard disk is normal, and changing the data cable of the hard disk can not solve the problem, and it is puzzling.

When I was confused, I suddenly remembered that there was a hard disk mode setting in the BIOS, so I booted into the BIOS and found four setting options related to the hard disk under Advanced Integrated Peripherals: "Primary" Master UDMA", "Primary Slave UDMA", "Secondary Master UDMA" and "Secondary Master UDMA". The above four items are all set to "Disabled", I tried to set them all to "Auto", and then use Ghost after exiting, everything is back to normal, the original problem is here!

May be repaired computer not long ago Set these four items to "Disabled" (the default should be "Enable"), which is hereby recorded for friends who also use the DOS version of Ghost.

UDMA mode:

UDMA mode is a data transmission mode, which has a higher burst data transmission speed of the I/O system and can also reduce the CPU resources of the I/O system. Occupancy rate.

In addition to setting in the BIOS, we can also expand the "IDE ATA/ATAPI Controller" branch in the device manager of the computer, and select "IDE Controller", "Main IDE Channel" and "Second" respectively. To enable DMA, select the "Advanced Settings → Enable DMA" option in the IDE channel "Two Properties Settings".
