Modify URLs to use https instead of http.
Remove ancient URLs that don't work.
Change "scsi" in text to "SCSI".
Change "cdrom" in text to "CD-ROM".
Drop the reference to "autoclean" for modules since I can't
  find it in any current documentation.

Notes on using modules in the SCSI subsystem

The SCSI support in the Linux kernel can be modularized in a number of
different ways depending upon the needs of the end user. To understand
your options, we should first define a few terms.
The scsi-core (also known as the "mid level") contains the core of scsi
support. Without it you can do nothing with any of the other scsi drivers.
The scsi core support can be a module (scsi_mod.o), or it can be built into

The scsi-core (also known as the "mid level") contains the core of SCSI
support. Without it you can do nothing with any of the other SCSI drivers.
The SCSI core support can be a module (scsi_mod.o), or it can be built into
the kernel. If the core is a module, it must be the first SCSI module
loaded, and if you unload the modules, it will have to be the last one
unloaded. In practice the modprobe and rmmod commands (and "autoclean")
unloaded. In practice the modprobe and rmmod commands
will enforce the correct ordering of loading and unloading modules in
the SCSI subsystem.
The individual upper and lower level drivers can be loaded in any order
once the scsi core is present in the kernel (either compiled in or loaded
as a module). The disk driver (sd_mod.o), cdrom driver (sr_mod.o),
tape driver [1]_ (st.o) and scsi generics driver (sg.o) represent the upper

tape driver [1]_ (st.o) and SCSI generics driver (sg.o) represent the upper
level drivers to support the various assorted devices which can be
controlled. You can for example load the tape driver to use the tape drive,
and then unload it once you have no further need for the driver (and release
