Linux-2.6.12-rc2v2.6.12-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!

11 | ---help--- | ||
12 | If you say Y here, your kernel will be able to manage low cost mass | ||
13 | storage units such as ATA/(E)IDE and ATAPI units. The most common | ||
14 | cases are IDE hard drives and ATAPI CD-ROM drives. | ||
15 | |||
16 | If your system is pure SCSI and doesn't use these interfaces, you | ||
17 | can say N here. | ||
18 | |||
19 | Integrated Disk Electronics (IDE aka ATA-1) is a connecting standard | ||
20 | for mass storage units such as hard disks. It was designed by | ||
21 | Western Digital and Compaq Computer in 1984. It was then named | ||
22 | ST506. Quite a number of disks use the IDE interface. | ||
23 | |||
24 | AT Attachment (ATA) is the superset of the IDE specifications. | ||
25 | ST506 was also called ATA-1. | ||
26 | |||
27 | Fast-IDE is ATA-2 (also named Fast ATA), Enhanced IDE (EIDE) is | ||
28 | ATA-3. It provides support for larger disks (up to 8.4GB by means of | ||
29 | the LBA standard), more disks (4 instead of 2) and for other mass | ||
30 | storage units such as tapes and cdrom. UDMA/33 (aka UltraDMA/33) is | ||
31 | ATA-4 and provides faster (and more CPU friendly) transfer modes | ||
32 | than previous PIO (Programmed processor Input/Output) from previous | ||
33 | ATA/IDE standards by means of fast DMA controllers. | ||
34 | |||
35 | ATA Packet Interface (ATAPI) is a protocol used by EIDE tape and | ||
36 | CD-ROM drives, similar in many respects to the SCSI protocol. | ||
37 | |||
38 | SMART IDE (Self Monitoring, Analysis and Reporting Technology) was | ||
39 | designed in order to prevent data corruption and disk crash by | ||
40 | detecting pre hardware failure conditions (heat, access time, and | ||
41 | the like...). Disks built since June 1995 may follow this standard. | ||
42 | The kernel itself doesn't manage this; however there are quite a | ||
43 | number of user programs such as smart that can query the status of | ||
44 | SMART parameters from disk drives. | ||
45 | |||
46 | To compile this driver as a module, choose M here: the | ||

102 | There are two drivers for Serial ATA controllers. | ||

1036 | There are two drivers for MFM/RLL/IDE hard disks. Most people use | ||
1037 | the newer enhanced driver, but this old one is still around for two | ||
1038 | reasons. Some older systems have strange timing problems and seem to | ||
1039 | work only with the old driver (which itself does not work with some | ||
1040 | newer systems). The other reason is that the old driver is smaller, | ||
1041 | since it lacks the enhanced functionality of the new one. This makes | ||
1042 | it a good choice for systems with very tight memory restrictions, or | ||
1043 | for systems with only older MFM/RLL/ESDI drives. Choosing the old | ||
1044 | driver can save 13 KB or so of kernel memory. | ||
1045 | |||
1046 | If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver | ||
1047 | instead of this one. For more detailed information, read the | ||
