=== lt_hotswap ===
The <tt>lt_hotswap</tt> kernel module enables hot-swapping for disk drives with full DMA support under Linux.
It should work on any ThinkPad with hot-swappable bays and ACPI support. The driver needs [[ibm-acpi]] to be running.
|}
===Features===
*enable hotswapping of [[UltraBay]] drives
*automatic IDE unregistering on [[ibm-acpi]] eject event
*leaves DMA support intact

===Limitations===
*does '''not''' work with APM

===Project Homepage / Availability===
*Project page: http://www.sourceforge.net/projects/lths
*Latest version: http://prdownloads.sourceforge.net/lths/lt_hotswap-0.3.6.tar.gz?download

Development and discussion of lt_hotswap is currently being held in
[[Mailinglists#Linux-ThinkPad Mailinglist|Linux-ThinkPad Mailinglist]].

===Installation===
In order to use the driver you must use ACPI and also have the [[ibm-acpi]] driver linked to your kernel (module or compiled).

When loading the hotswap module, you can use the module parameter: {{bootparm|auto_eject|1}} to automatically unregister the drives IDE interface. This will happen upon popping out the [[UltraBay]] lever.

===Supported models===
The driver has been explicitly reported to work on the following models. It should work on many others as well:
*ThinkPad {{A31p}} (warmswap), {{T22}}, {{T40}}, {{T42}}

The <tt>lt_hotswap</tt> driver will not work if you use the <tt>ata_piix</tt> driver rather than the generic IDE driver (<tt>ata_piix</tt> is necessary on some models to get DMA support, see [[problems with SATA and Linux]]).
