Tertiary and quaternary IDE
|
|
===========================
|
|
|
|
The additional tertiary and quaternary IDE controllers, enabled through the :ref:`settings/peripherals:Tertiary / Quaternary IDE Controller` settings, may require manual configuration of guest operating systems, which is outlined in this page. They are also **not bootable**, except on machines equipped with MR BIOS.
|
|
|
|
The following system resources are used by these additional controllers:
|
|
|
|
+----------+-------------+---------------+---+
|
|
|Channel |Main I/O port|Status I/O port|IRQ|
|
|
+==========+=============+===============+===+
|
|
|Tertiary |0168h |036Eh |10 |
|
|
+----------+-------------+---------------+---+
|
|
|Quaternary|01E8h |03EEh |11 |
|
|
+----------+-------------+---------------+---+
|
|
|
|
.. note:: While the IRQ for each channel can be changed through its respective *Settings* button on :ref:`settings/peripherals:Tertiary / Quaternary IDE Controller`, most operating systems do not allow legacy (ISA or VLB) IDE controllers to use custom IRQs.

BIOS support
|
|
------------
|
|
|
|
The tertiary and quaternary controllers are only supported (partially or fully) by some BIOSes. The following table lists all BIOSes emulated by 86Box which are known to support these controllers:
|

Windows NT, 2000, XP and newer
|
|
------------------------------
|
|
|
|
The Windows NT family will detect and enable both additional channels at installation time *only if* supported by the BIOS (see the *Windows NT support?* column on :ref:`the table above <bios>`).
|
|
|
|
.. note:: If you install the system to a hard disk on one of the additional channels, it will not be bootable if the BIOS doesn't support booting from these channels (see the *Bootable?* column).
|
|
|
|
Alternatively, the additional channels can be enabled after the system is installed:
|
|
|
|
* **Windows NT 4.0:** TBD.
|
|
* **Windows 2000:** go to the *Add New Hardware* control panel and add a *Generic IDE/ESDI Hard Disk Controller* device for each additional channel. Configuration 000x corresponds to the **tertiary** channel, while Configuration 000x corresponds to the **quaternary** channel.
|
|
* **Windows XP:** TBD. (IDE/ESDI not listed - let PnP do the job?)

-----
|
|
|
|
On kernels 2.6.19 and newer (after the switch to ``libata``), run the ``modprobe pata_legacy probe_all=1`` command as root to enable both additional channels. Consult your distribution's documentation on how to load that module on startup.
|
|
|
|
On kernels older than 2.6.19 (before the switch to ``libata``), add the following parameters to the kernel command line to enable their respective channels:
|
|
|
|
* **Tertiary:** ``ide2=0x168,0x36e,10`` (assuming IRQ 10)
|
|
* **Quaternary:** ``ide3=0x1e8,0x3ee,11`` (assuming IRQ 11)
