In many cases, you'll have to do your first boot from floppy disks,
|
| 11 |
using the rescue floppy. Generally, all you will need is a

|
| 33 |
support booting from a CD-ROM, you can use the CD-ROM in conjunction
|
| 34 |
with the other techniques to install your system, once you've booted
|

up by other means; see <xref linkend="install-cd"></xref>.

Both SCSI and IDE/ATAPI CD-ROMs are supported. In addition, all
|
| 44 |
non-standard CD interfaces supported by Linux are supported by the
|
| 45 |
boot disks (such as Mitsumi and Matsushita drives). However, these
|
| 46 |
models might require special boot parameters or other massaging to get
|
| 47 |
them to work, and booting off these non-standard interfaces is
|
| 48 |
unlikely. The <ulink url="&url-cd-howto;">Linux CD-ROM HOWTO</ulink>

On DECstations, booting from CD-ROM requires a SCSI CD-ROM drive
|
| 66 |
capable of working with a logical blocksize of 512 bytes. Many of the
|
| 67 |
SCSI CD-DROM drives sold for the PC market do not have this
|
| 68 |
capability. If your CD-ROM drive has a jumper labeled "Unix/PC" or
|
| 69 |
"512/2048", place it in the "Unix" or "512" position.

The Debian boot disks contain a kernel which is built to maximize the
|
| 134 |
number of systems it runs on. Unfortunately, this makes for a larger
|
| 135 |
kernel, which includes many drivers that won't be used for your
|
| 136 |
machine (see <xref linkend="kernel-baking"></xref> to learn how to
|
| 137 |
build your own kernel). Support for the widest possible range of
|
| 138 |
devices is desirable in general, to ensure that Debian can be
|
| 139 |
installed on the widest array of hardware.
