Abstract
This invention is provided to simplify building a personal computer having a CD-ROM apparatus as an external memory and using an IDE-BUS I/F for connecting to the CD-ROM apparatus. Thus, a hard disk unit is connected to a master partition of the IDE-BUS I/F of the personal computer, and the CD-ROM apparatus is connected to a slave partition of the IDE-BUS I/F.
Claims2
A CD-ROM apparatus comprising an IDE interface, wherein a hard disk unit and said CD-ROM apparatus are connected in cascade by a master and slave device with an IDE interface of a personal computer, and wherein said master and slave device is controlled by a CD-ROM software driver switching a drive select bit in the IDE interface so that said CD-ROM apparatus may be used as said master or slave device.
A personal computer system, comprising:
- an IDE interface provided in a personal computer;
- an IDE BUS connected to said IDE interface of said personal computer;
- a CD-ROM apparatus containing an IDE interface which can be directly connected to said IDE interface of said personal computer through said IDE BUS;
- and
- a hard disk having an IDE interface which also can be directly connected to said IDE interface of said personal computer through said IDE BUS;
- wherein said CD-ROM apparatus and hard disk unit are connected in cascade by a master and slave device with said IDE interface of said personal computer, and wherein said master and slave device is controlled by a CD-ROM software driver switching a drive selection bit in the IDE interface so that said CD-ROM apparatus may be used as said master or slave device.
