| 13 | If you say Y here, you will get support for terminal devices with |
| 14 | display and keyboard devices. These are called "virtual" because you |
| 15 | can run several virtual terminals (also called virtual consoles) on |
| 16 | one physical terminal. This is rather useful, for example one |
| 17 | virtual terminal can collect system messages and warnings, another |
| 18 | one can be used for a text-mode user session, and a third could run |
| 19 | an X session, all in parallel. Switching between virtual terminals |
| 20 | is done with certain key combinations, usually Alt-<function key>. |
| 21 | |
| 22 | The setterm command ("man setterm") can be used to change the |
| 23 | properties (such as colors or beeping) of a virtual terminal. The |
| 24 | man page console_codes(4) ("man console_codes") contains the special |
| 25 | character sequences that can be used to change those properties |
| 26 | directly. The fonts used on virtual terminals can be changed with |
| 27 | the setfont ("man setfont") command and the key bindings are defined |
| 28 | with the loadkeys ("man loadkeys") command. |
| 29 | |
| 30 | You need at least one virtual terminal device in order to make use |
| 31 | of your keyboard and monitor. Therefore, only people configuring an |
| 32 | embedded system would want to say N here in order to save some |
| 33 | memory; the only way to log into such a system is then via a serial |
| 34 | or network connection. |
| 35 | |
| 36 | If unsure, say Y, or else you won't be able to do much with your new |
| 37 | shiny Linux system :-) |

| 61 | terminal (/dev/tty0) will be used as system console. You can change |

| 530 | It is possible to share one parallel port among several devices |

| 540 | how to pass options to the kernel at boot time.) The syntax of the |

| 554 | |
| 555 | If the printer is out of paper (or off, or unplugged, or too |
| 556 | busy..) the kernel will stall until the printer is ready again. |
| 557 | By defining CONSOLE_LP_STRICT to 0 (at your own risk) you |

| 742 | and most Ataris. The actual number of bytes varies, depending on the |
| 743 | nvram in the system, but is usually 114 (128-14 for the RTC). |
| 744 | |
| 745 | This memory is conventionally called "CMOS RAM" on PCs and "NVRAM" |
| 746 | on Ataris. /dev/nvram may be used to view settings there, or to |
| 747 | change them (with some utility). It could also be used to frequently |
| 748 | save a few bits of very important data that may not be lost over |
| 749 | power-off and for which writing to disk is too insecure. Note |
| 750 | however that most NVRAM space in a PC belongs to the BIOS and you |
| 751 | should NEVER idly tamper with it. See Ralf Brown's interrupt list |
| 752 | for a guide to the use of CMOS bytes by your BIOS. |
| 753 | |
| 754 | On Atari machines, /dev/nvram is always configured and does not need |
