Supported Products / Systems (ie integrated into PC System):
Other ATAPI 1.2 compliant CD-ROM drives should work with NEXTSTEP even if they are not in the supported list. If a CD-ROM drive does not work with NEXTSTEP (or even if it does) we would like to know about it. Please send an email message to including the model number of the CD-ROM drive and also whether this drive is connected as a master or a slave.

Special Features of Driver / Driver Notes:
Also see the NextAnswer 1933_EIDE_and_ATAPI_CDROM_Support_in_NEXTSTEP_3.3

NeXT's EIDE driver is not affected by the RZ1000 hardware bug.

This device driver provides information in the Configure application's help panel. Choose Info>Help from the Configure menu and scroll down to find this device driver's help topic.

Known Problems

These devices are not supported.
1. NEC CDR-260 (2X)
2. NEC CDR-273

To get the Pioneer DR-UA124X 1.02 CD-ROM to work you must force detection. You can do this by going in Expert mode and adding the key "Slave"="ATAPI" (or "Master" as the case may be) to the table.

Driver versions 3.33 and below can cause certain systems to hang under very heavy load.

Due to ongoing development and testing of OPENSTEP 4.0, the beta version (v3.34) of this driver will neither be tested on NEXTSTEP 3.3 nor upgraded to "Released" status.

Driver Version Notes

3.33: This version adds support for several new ATAPI CD-ROM drives and fixes some bugs.
3.34: Fixed a bug which could cause machines to hang under very heavy load.
3.36: Added device overrides and modified the inspector. The new overrides are documented in the driver help.
3.37: Improved ATAPI support. Added support for Intel PIIX PCI IDE controllers. Added Bus Master support. Revised the driver Inspector.

Future Planning

Reason for New Driver / Update:
New Driver / Update Timeframe:

New Driver / Update Description:
Use the following installation instructions when installing from a CD-ROM drive connected to the secondary EIDE controller:

1. Select Primary/Secondary(Dual) EIDE and ATAPI
Device Controllers as the hard disk driver.

2. After the install program has finished reading
from the CD-ROM, the Configure panel will
appear. Double-click the Other icon. If the
Primary/Secondary(Dual) EIDE and ATAPI
Device Controllers driver is listed, remove it from
the list. It is no longer necessary since the
installation from the CD-ROM is complete. Add the
appropriate EIDE driver to match your EIDE
hardware configuration. You will need to add it
twice to get a second instance of the EIDE
driver to support the secondary EIDE
controller. You will need to set the IRQ to 15, and
I/O port address range to 0x170-0x177 in the
second instance of the driver, in order to avoid
conflicts with the first instance. Add any other
necessary drivers while in Configure, and then
click on theSave button.

Note: Information contained in the "Future Planning" section of this document does not constitute a commitment on the part of NeXT to complete the planned development work.
