You may need to configure your hardware as indicated in
|
| 11 |
<xref linkend="boot-dev-select"/>. Then put the CD-ROM into the drive,
|
| 12 |
and reboot. The system should boot up, and you should be presented
|
| 13 |
with the <prompt>boot:</prompt> prompt. Here you can enter your
|
| 14 |
boot arguments, or just hit &enterkey;.

If your hardware doesn't support booting of multiple images, put one
|
| 30 |
of the other CDs in the drive. It appears that most SCSI CD-ROM drives
|
| 31 |
do not support <command>isolinux</command> multiple image booting, so users
|
| 32 |
with SCSI CD-ROMs should try either CD2 (vanilla) or CD3 (compact),

| 33 |
or CD5 (bf2.4).

CD's 2 through 5 will each boot a

If your system can't boot directly from CD-ROM, or you simply can't
|
| 83 |
seem to get it to work, don't despair; you can simply run
|
| 84 |
<command>E:\install\boot.bat</command> under DOS (replace
|
| 85 |
<userinput>E:</userinput> with whatever drive letter DOS assigns to
|
| 86 |
your CD-ROM drive) to start the installation process. Then, skip down

Also, if you're going to be installing from a FAT (DOS) partition, you

have the option of booting the installer from the hard disk. See

installing via this method.

06:38 < SuperQ> anyone done much with d-i on pxe boot?
|
| 427 |
06:39 < SuperQ> I got it all setup, daily build from sjogren's files
|
| 428 |
06:39 < joshk> yes, it works
|
| 429 |
06:39 < SuperQ> "Warning: unable to open an initial console."

06:39 < SuperQ> Kernel panic: Attempted to kill init!
|
| 431 |
06:39 < joshk> pass devfs=mount to the kernel
|

06:40 < joshk> in pxelinux.cfg/whatever
|
| 433 |
06:40 < SuperQ> oh.. that's changed since the bug tracking post

06:40 < SuperQ> http://lists.debian.org/debian-testing/2003/debian-testing-200311/msg00098.html
|
| 435 |
06:40 < SuperQ> that says to devfs=nomount
|
| 436 |
06:41 < SuperQ> should probably copy the bulk of that message into

06:41 < joshk> that's from months ago

06:41 < SuperQ> I know
|
| 442 |
06:42 < SuperQ> but it's still referanced in the howto
|
| 443 |
06:42 < SuperQ> yay! it works now
|
| 444 |
06:42 * SuperQ gives his new ThinkPad X31 some sarge love
|
| 445 |
06:42 < SuperQ> I'll have to write up a page on Sarge/D-I and things for

If you are booting from the boot floppy or from CD-ROM you will be
|
| 457 |
presented with the boot prompt, <prompt>boot:</prompt>. Details
|
| 458 |
about how to use boot parameters with the boot floppy can be found
|
| 459 |
in <xref linkend="floppy-boot"/>. If you are booting from an
|
| 460 |
existing operating system, you'll have to use other means to set boot
|
| 461 |
parameters. For instance, if you are installing from DOS, you can
|
| 462 |
edit the <filename>install.bat</filename> file with any text editor.

Some systems have floppies with ``inverted DCLs''. If you receive
|
| 467 |
errors reading from the floppy, even when you know the floppy is good,
|
| 468 |
try the parameter <userinput>floppy=thinkpad</userinput>.

On some systems, such as the IBM PS/1 or ValuePoint (which have ST-506
|
| 473 |
disk drivers), the IDE drive may not be properly recognized. Again,
|
| 474 |
try it first without the parameters and see if the IDE drive is
|
| 475 |
recognized properly. If not, determine your drive geometry
|
| 476 |
(cylinders, heads, and sectors), and use the parameter
|
| 477 |
<userinput>hd=<replaceable>cylinders</replaceable>,<replaceable>heads</replaceable>,<replaceable>sectors</replaceable></userinput>.

If you have a very old machine, and the kernel hangs after saying
|
| 482 |
<computeroutput>Checking 'hlt' instruction...</computeroutput>, then
|
| 483 |
you should try the <userinput>no-hlt</userinput> boot argument, which
|
| 484 |
disables this test.

If your screen begins to show a weird picture while the kernel boots,
|
| 489 |
eg. pure white, pure black or colored pixel garbage, your system may
|
| 490 |
contain a problematic video card which does not switch to the
|
| 491 |
framebuffer mode properly. Then you can use the boot parameter
|
| 492 |
<userinput>video=vga16:off</userinput> to disable the framebuffer
|
| 493 |
console. The language chooser will not appear; only the english
|
| 494 |
language will be available during the installation due to limited
|
| 495 |
console features. See <xref linkend="boot-parms"/> for details.

<title>System freeze while loading the USB modules</title>

<para>

The kernel normaly tries to install the USB and USB keyboard driver in
|
| 543 |
order to allow the installation for users of some non-standard USB keyboards.
|
| 544 |
However, there are few broken USB systems where the driver hangs on loading. A
|
| 545 |
possible workaround may be disabling of the USB controller in your mainboard
|
| 546 |
BIOS setup. Another way is passing the <userinput>nousb</userinput>
|
| 547 |
argument on the boot prompt, which will prevent the modules from
|
| 548 |
beeing loaded even if USB hardware has been detected.
