Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ ---help---
+ If you say Y here, your kernel will be able to manage low cost mass
+ storage units such as ATA/(E)IDE and ATAPI units. The most common
+ cases are IDE hard drives and ATAPI CD-ROM drives.
+
+ If your system is pure SCSI and doesn't use these interfaces, you
+ can say N here.
+
+ Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard
+ for mass storage units such as hard disks. It was designed by
+ Western Digital and Compaq Computer in 1984. It was then named
+ ST506. Quite a number of disks use the IDE interface.
+
+ AT Attachment (ATA) is the superset of the IDE specifications.
+ ST506 was also called ATA-1.
+
+ Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is
+ ATA-3. It provides support for larger disks (up to 8.4GB by means of
+ the LBA standard), more disks (4 instead of 2) and for other mass
+ storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is
+ ATA-4 and provides faster (and more CPU friendly) transfer modes
+ than previous PIO (Programmed processor Input/Output) from previous
+ ATA/IDE standards by means of fast DMA controllers.
+
+ ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and
+ CD-ROM drives, similar in many respects to the SCSI protocol.
+
+ SMART IDE (Self Monitoring, Analysis and Reporting Technology) was
+ designed in order to prevent data corruption and disk crash by
+ detecting pre hardware failure conditions (heat, access time, and
+ the like...). Disks built since June 1995 may follow this standard.
+ The kernel itself doesn't manage this; however there are quite a
+ number of user programs such as smart that can query the status of
+ SMART parameters from disk drives.
+
+ To compile this driver as a module, choose M here: the
+ module will be called ide.
+
+ For further information, please read <file:Documentation/ide.txt>.
+

+ "master" and a "slave" device, for a total of up to twenty ATA/IDE
+ disk/cdrom/tape/floppy drives.
+
+ Useful information about large (>540 MB) IDE disks, multiple
+ interfaces, what to do if ATA/IDE devices are not automatically
+ detected, sound card ATA/IDE ports, module support, and other
+ topics, is contained in <file:Documentation/ide.txt>. For detailed
+ information about hard drives, consult the Disk-HOWTO and the
+ Multi-Disk-HOWTO, available from

+
+ If you have one or more IDE drives, say Y or M here. If your system
+ has no IDE drives, or if memory requirements are really tight, you
+ could say N here, and select the "Old hard disk driver" below

+ There are two drivers for MFM/RLL/IDE disks. Most people use just
+ the new enhanced driver by itself. This option however installs the
+ old hard disk driver to control the primary IDE/disk interface in
+ the system, leaving the new enhanced IDE driver to take care of only
+ the 2nd/3rd/4th IDE interfaces. Doing this will prevent you from
+ having an IDE/ATAPI CD-ROM or tape drive connected to the primary

+
+ This will provide SCSI host adapter emulation for IDE ATAPI devices,
+ and will allow you to use a SCSI device driver instead of a native

+
+ This is useful if you have an ATAPI device for which no native

+ you can then use this emulation together with an appropriate SCSI
