If I remember correctly, Solaris would want to format the primary drive but it should tell you which one it is doing. I believe it 'finds' the Windows partition and asks if you want to save it.

The only SURE way to insure you don't overwrite your C drive is to remove it (disconnect) and connect your new drive when loading Solaris. Then reconnect it as originally installed. You may have a problem booting to Solaris this way but you certainly won't overwrite your Windows.

From SunSolve (Sept 1996):

How do I setup for multiple operating systems?

The Solaris OS allows you to boot up to four (4) operating
systems on the same hard drive. Solaris will make itself the
'active' partition of the drive and at boot time will present you
with a boot menu. The following are some ideas about setting up
some of the more common configurations found in PC systems:

"I want DOS and Solaris on my system and only have one hard drive".

First, setup a DOS partition of xxx mb, then leave the rest of the drive
un-partitioned. When you see the question about how much of the drive to
use, select what is available.

"I have drive 'C' setup for DOS/Windows and I want Solaris on drive 'D'.

This will work just fine but you will not be able to boot Solaris without
using the install/boot floppies. You could also boot Solaris if you have a
third-party boot manager such as 'System Commander' from V Communications.
This type of package will allow you to boot to your DOS drive or boot
Solaris on your second hard drive.

"I want to install Solaris, NT and Windows95 on the same drive".

In this case, install NT, WIN95 and then Solaris x86. Both NT and Windows95
like to take over and be the primary boot OS for the system. The Solaris
boot manager will allow you to boot into any of the three operating systems.
You will also be able to mount the NT and Windows95 partition if the NT
partition is not NTFS (NT File System). Solaris can see NT, Windows95, and
DOS partitions.

cmdk(7D)							      Devices								  cmdk(7D)

NAME

       cmdk - common disk driver

SYNOPSIS

       cmdk@target, lun : [ partition | slice ]

DESCRIPTION

       The  cmdk  device  driver  is  a  common interface to various disk devices. The driver supports magnetic fixed disks and magnetic removable
       disks.

       The cmdk device driver supports three different disk labels: fdisk partition table, Solaris x86 VTOC and EFI/GPT.

       The block-files access the disk using the system's normal buffering mechanism and are read and written  without	regard	to  physical  disk
       records. There is also a "raw" interface that provides for direct transmission between the disk and the user's read or write buffer. A sin-
       gle read or write call usually results in one I/O operation; raw I/O is therefore considerably more efficient when many bytes are transmit-
       ted. The names of the block files are found in /dev/dsk. Raw file names are found in /dev/rdsk.

       I/O  requests  to the magnetic disk must have an offset and transfer length that is a multiple of 512 bytes or the driver returns an EINVAL
       error.

       Slice 0 is normally used for the root file system on a disk, slice 1 as a paging area (for example, swap), and slice 2 for backing  up  the
       entire fdisk partition for Solaris software. Other slices may be used for usr file systems or system reserved area.

       The fdisk partition 0 is to access the entire disk and is generally used by the fdisk(1M) program.

FILES

       /dev/dsk/cndn[s|p]n	 block device (IDE)

       /dev/rdsk/cndn[s|p]n	 raw device (IDE)

				 where:

				 cn    controller n.

				 dn    lun n (0-1).

				 sn    UNIX system slice n (0-15).

				 pn    fdisk partition (0-36).

       /kernel/drv/cmdk 	 32-bit kernel module.
