<title>Alternative: Using LILO</title> |
| 437 |
<subsection> |
| 438 |
<title>Installing LILO</title> |
| 439 |
<body> |
| 440 |
|
| 441 |
<p> |
| 442 |
LILO, the LInuxLOader, is the tried and true workhorse of Linux |
| 443 |
bootloaders. However, it lacks some features that GRUB has (which is |
| 444 |
also the reason why GRUB is currently gaining popularity). The reason |
| 445 |
why LILO is still used is that, on some systems, GRUB doesn't work and |
| 446 |
LILO does. Of course, it is also used because some people know LILO and |
| 447 |
want to stick with it. Either way, Gentoo supports both, and apparently |
| 448 |
you have chosen to use LILO. |
| 449 |
</p> |
| 450 |
|
| 451 |
<p> |
| 452 |
Installing LILO is a breeze; just use <c>emerge</c>. |
| 453 |
</p> |
| 454 |

| 455 |

<title>Configuring LILO</title> |
| 463 |
<body> |
| 464 |
|
| 465 |
<p> |
| 466 |
To configure LILO, you must create <path>/etc/lilo.conf</path>. Fire up |
| 467 |
your favorite editor (in this handbook we use <c>nano</c> for |
| 468 |
consistency) and create the file. |
| 469 |
</p> |
| 470 |
|
| 471 |
<pre caption="Creating /etc/lilo.conf"> |
| 472 |
# <i>nano -w /etc/lilo.conf</i> |
| 473 |
</pre> |
| 474 |
|
| 475 |
<p> |
| 476 |
Some sections ago we have asked you to remember the kernel-image name |
| 477 |
you have created. In the next example <path>lilo.conf</path> we use the |
| 478 |
example partitioning scheme. There are two separate parts: |
| 479 |
</p> |
| 480 |
|
| 481 |
<ul> |
| 482 |
<li> |
| 483 |
One for those who have not used <c>genkernel</c> to build their kernel |
| 484 |
</li> |
| 485 |
<li> |
| 486 |
One for those who have used <c>genkernel</c> to build their kernel |
| 487 |
</li> |
| 488 |
</ul> |
| 489 |
|
| 490 |
<p> |
| 491 |
Make sure you use <e>your</e> kernel image filename and, if appropriate, |
| 492 |
<e>your</e> initrd image filename. |
| 493 |
</p> |
| 494 |
|
| 495 |
<note> |
| 496 |
If your root filesystem is JFS, you <e>must</e> add a <c>append="ro"</c> |
| 497 |
line after each boot item since JFS needs to replay its log before it allows |
| 498 |
read-write mounting. |
| 499 |

| 532 |
|
| 533 |
<note> |
| 534 |
If you use a different partitioning scheme and/or kernel image, adjust |
| 535 |
accordingly. |
| 536 |
</note> |
| 537 |
|
| 538 |
<p> |
| 539 |
If you need to pass any additional options to the kernel, add an |
| 540 |
<c>append</c> statement to the section. As an example, we add the |
| 541 |
<c>video</c> statement to enable framebuffer: |
| 542 |
</p> |
| 543 |
|
| 544 |
<pre caption="Using append to add kernel options"> |
| 545 |
image=/boot/<keyval id="kernel-name"/> |
| 546 |
label=gentoo |
| 547 |
read-only |

root=/dev/sda3 |
| 549 |
<i>append="video=uvesafb:mtrr,ywrap,1024x768-32@85"</i> |
| 550 |
</pre> |
| 551 |
|
| 552 |
<p> |
| 553 |
If you're using a 2.6.7 or higher kernel and you jumpered your harddrive |
| 554 |
because the BIOS can't handle large harddrives you'll need to append |
| 555 |
<c>sda=stroke</c>. Replace sda with the device that requires this option. |
| 556 |
</p> |
| 557 |
|
| 558 |
<p> |
| 559 |
<c>genkernel</c> users should know that their kernels use the same boot options |
| 560 |
as is used for the Installation CD. For instance, if you have SCSI devices, you |
| 561 |
should add <c>doscsi</c> as kernel option. |
| 562 |
</p> |
| 563 |
|
| 564 |
<p> |
| 565 |
Now save the file and exit. To finish up, you have to run <c>/sbin/lilo</c> so |
| 566 |
LILO can apply the <path>/etc/lilo.conf</path> to your system (i.e. install |
| 567 |
itself on the disk). Keep in mind that you'll also have to run |
| 568 |
<c>/sbin/lilo</c> every time you install a new kernel or make any changes to |
| 569 |
the menu. |
| 570 |
</p> |
| 571 |
|
| 572 |
