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!

24 you'll need this, unless you have a different type keyboard (USB, ADB
25 or other). This also works for AT and PS/2 keyboards connected over a

49 If you have an RDI PrecisionBook, say Y here if you want to use its
50 built-in keyboard (as opposed to an external keyboard).
51
52 The PrecisionBook has five keys that conflict with those used by most
53 AT and PS/2 keyboards. These are as follows:
54
55 PrecisionBook Standard AT or PS/2
56
57 F1 F12
58 Left Ctrl Left Alt
59 Caps Lock Left Ctrl
60 Right Ctrl Caps Lock
61 Left 102nd key (the key to the right of Left Shift)
62
63 If you say N here, and use the PrecisionBook keyboard, then each key
64 in the left-hand column will be interpreted as the corresponding key
65 in the right-hand column.
66
67 If you say Y here, and use an external keyboard, then each key in the
68 right-hand column will be interpreted as the key shown in the
69 left-hand column.

160 The "Human Interface Loop" is a older, 8-channel USB-like
161 controller used in several Hewlett Packard models. This driver
162 was adapted from the one written for m68k/hp300, and implements
163 support for a keyboard attached to the HIL port, but not for
164 any other types of HIL input devices like mice or tablets.
165 However, it has been thoroughly tested and is stable.
166
167 If you want full HIL support including support for multiple
168 keyboards, mices and tablets, you have to enable the
169 "HP System Device Controller i8042 Support" in the input/serio
170 submenu.

10 * DEC LK201 and LK401 keyboard driver for Linux (primary for DECstations
11 * and VAXstations, but can also be used on any standard RS232 with an
12 * adaptor).
13 *
14 * DISCLAIMER: This works for _me_. If you break anything by using the
15 * information given below, I will _not_ be liable!
16 *
17 * RJ10 pinout: To DE9: Or DB25:
18 * 1 - RxD <----> Pin 3 (TxD) <-> Pin 2 (TxD)
19 * 2 - GND <----> Pin 5 (GND) <-> Pin 7 (GND)
20 * 4 - TxD <----> Pin 2 (RxD) <-> Pin 3 (RxD)
21 * 3 - +12V (from HDD drive connector), DON'T connect to DE9 or DB25!!!
22 *
23 * Pin numbers for DE9 and DB25 are noted on the plug (quite small:). For
24 * RJ10, it's like this:
25 *
26 * __=__ Hold the plug in front of you, cable downwards,
27 * /___/| nose is hidden behind the plug. Now, pin 1 is at
28 * |1234|| the left side, pin 4 at the right and 2 and 3 are
29 * |IIII|| in between, of course:)
30 * | ||
31 * |____|/
32 * || So the adaptor consists of three connected cables
33 * || for data transmission (RxD and TxD) and signal ground.
34 * Additionally, you have to get +12V from somewhere.
35 * Most easily, you'll get that from a floppy or HDD power connector.
36 * It's the yellow cable there (black is ground and red is +5V).
37 *
38 * The keyboard and all the commands it understands are documented in
39 * "VCB02 Video Subsystem - Technical Manual", EK-104AA-TM-001. This
40 * document is LK201 specific, but LK401 is mostly compatible. It comes
41 * up in LK201 mode and doesn't report any of the additional keys it
42 * has. These need to be switched on with the LK_CMD_ENABLE_LK401
43 * command. You'll find this document (scanned .pdf file) on MANX,
44 * a search engine specific to DEC documentation. Try
45 * http://www.vt100.net/manx/details?pn=EK-104AA-TM-001;id=21;cp=1
