Auto-Detected Drive Parameters
The “grayed-out” items in the left frame are IDE disk drive parameters automatically
detected from the firmware of the selected IDE disk drive. The drive parameters are listed
as follows:
Device: Lists the device type (e.g. hard disk, CD-ROM etc.)
Vendor: Lists the device manufacturer
Size: The size of the device.
LBA Mode: Indicates whether the LBA (Logical Block Addressing) is a method
of addressing data on a disk drive is supported or not.
Block Mode: Block mode boosts IDE drive performance by increasing the
amount of data transferred. Only 512 bytes of data can be transferred per
interrupt if block mode is not used. Block mode allows transfers of up to 64 KB
