1.6.3 IDE Support
The YA810E board has two independent bus-mastering IDE interfaces. These interfaces support:
•
ATAPI devices (such as CD-ROM drives)
•
ATA devices using the transfer modes listed in Table 56 on page 85
The BIOS supports logical block addressing (LBA) and extended cylinder head sector (ECHS)
translation modes. The drive reports the transfer rate and translation mode to the BIOS.
The YA810E board supports laser servo (LS-120) diskette technology through its IDE interfaces.
The LS-120 drive can be configured as a boot device by setting the BIOS Setup program's Boot
menu to one of the following:
•
ARMD-FDD (ATAPI removable media device – floppy disk drive)
•
ARMD-HDD (ATAPI removable media device – hard disk drive)
The board has two IDE interface connectors. The primary IDE connector is a standard 40-pin IDE
interface. The secondary IDE connector is a 50-pin Slimline IDE connector, intended for use with
devices such as 2.5-inch hard disk drives and mobile CD-ROM drives. The Slimline IDE
connector has the standard IDE interface pins but also includes audio and power signals.
