5.1. Setup
This is a description of the salient features of the setup used to
develop the procedures described below. All the procedures have
been tried and tested, also for Linux-2.6. The screen-like
displays are precise copies of what appeared on my screen.
-
Hardware: Intel (R) Celeron (TM) 1100 MHz
-
Distribution: RedHat Linux 7.0 (extensively modified)
-
Kernel: Linux-2.4.20 (from www.kernel.org). See also
Section 12 for Linux-2.6.x.
-
Tools: util-linux-2.11z (mount, umount, fdisk);
e2fsprogs-1.32 (mke2fs, dumpe2fs, fsck.ext2);
mkdosfs-2.2
5.2. Kernel options
It is uncertain if USB-support is sufficient in kernels earlier
than 2.4.xx. The following support, relevant to this document, was
compiled into the kernel. A modular approach may also be followed.
5.2.1. SCSI support
- SCSI support (CONFIG_SCSI scsi_mod.o)
- SCSI disk support (CONFIG_BLK_DEV_SD sd_mod.o)
5.2.2. File systems
- DOS FAT fs support (CONFIG_FAT_FS fat.o)
- MSDOS fs support (CONFIG_MSDOS_FS msdos.o)
-
VFAT (Windows 95) fs support (CONFIG_VFAT_FS vfat.o)
- /proc filesystem (CONFIG_PROC_FS)
-
Second extended fs support (ext2fs) (CONFIG_EXT2_FS ext2.o)
5.2.3. USB support
- Support for USB (CONFIG_USB usbcore.o)
-
Preliminary USB device filesystem (CONFIG_USB_DEVICEFS)
-
USB Mass Storage support (CONFIG_USB_STORAGE usb-storage.o)
5.3. Notes
In the lists above the entities in uppercase refer to the
variable names to be found in the .config
file in the upper level directory of the kernel source (/usr/src/linux/). The entities
xxx.o refer to the modules created when a
modular approach is followed. When there is no reference to a
module, the option can only be hard-compiled into the kernel.
Different kernel versions may have different indications of
options when, for example, make menuconfig
or make xconfig are run. Variables such
as CONFIG_USB, which can be gleaned from the various
help options, may be a more reliable indication.
Very recent Linux distributions such as
RedHat and SuSE
probably have the appropriate kernel options compiled in.
Under USB-support, options for a number of digital cameras are
available.
Please consult the relevant texts as set out in
Section 4 if you consider (re)compiling your
kernel.
