This is a hacked version of the "sd" disk driver for Solaris 2.4 (sparc).

This driver supports:

	Sector sizes from 512 Bytes up to 8k
	WORM drives
	OPTICAL MEMORY drives (MO and phase change)


If you want to use a CD-recorder or a CD-drive that supports only 2048 Bytes
sector size as CD-ROM drive, do the following:

Make a dierectory /etc/kernel
make a directoey /etc/kernel/drv
copy sd and sd.conf from this this distribution to your local /etc/kernel/drv

copy /etc/system to /etc/system.ok

add a line:
	moddir: /etc/kernel /kernel /usr/kernel

to /etc/system

reboot.

If you want to use this driver with Solaris 2.5, you need a different entry
in /etc/system. On a Sparstation 20 this will be:

/etc/kernel /platform/SUNW,SPARCstation-20/kernel /kernel /usr/kernel

or

/etc/kernel /platform/sun4m/kernel /kernel /usr/kernel


BEWAE: If you make mistakes, you will probably not be able to reboot.

If you have problems, you must reboot with the -a flag
and answer the questions ...[/etc/system]...? with /etc/system.ok
all other questions should be answered with <return>.
