• IRQ Level: 15

• I/O Address: 0x170

If an IDE CD-ROM drive is installed, the system BIOS parameter for that device

should be:

• Drive Type: Not installed

If an enhanced IDE drive is installed, set the system BIOS as follows:

• Enhanced IDE Drive: Enabled

Note - If the BIOS supports autoconﬁguration, use this facility to set the number of

heads, cylinders, and sectors for the IDE hard disk drive. If this capability is not

supported by the BIOS, use the settings provided by the disk manufacturer.

Known Problems and Limitations

Most manufacturers restrict the BIOS size to less than 8 Gbytes even though the

disk drive may be larger than 8 Gbytes. Solaris Intel Platform Edition respects this

restriction when partitioning disk drives.

To work around this problem, move the drive to a secondary controller where it is

not a BIOS boot device, or use the remaining space on the drive for another

operating system.

The Panasonic LK_MC579B IDE CD-ROM drive cannot be used to install the

Solaris operating environment and is not supported.

Several vendors ship PCI-equipped machines with IDE interfaces on the

motherboard. A number of these machines use the CMD-604 PCI-IDE controller.

This chip provides two IDE interfaces. The primary IDE interface is at I/O address

0x1F0 and the secondary interface at 0x170. However, this chip cannot handle

simultaneous I/O on both IDE interfaces. This defect causes the Solaris software to

hang if both interfaces are used.

Use only the primary IDE interface at address 0x1F0. Machines using this chip

include DELL XPS/90, HP XU/590C, and American Megatrends Atlas boards.

You cannot boot from the third or fourth IDE disk drives, although you can install

Solaris software on them.

The Solaris Volume Management software does not work with the Sony CDU-55E

CD-ROM drive no matter how it is conﬁgured (as the master or the slave).
