Because you have a SCSI device.  Linux will probe for it unless told not to.
The DOS drivers are completely irrelevent.

Get the bare bootdisk instead of the scsi, scsinet, or scsicd one you have.
You can also try some of the boot options listed below:


This is a list of command line parameters recognized and interpreted by:
========================================================================

  1. LOADLIN
       ramdisk=size        (size in Kbytes)
     or
       ramdisk=size,no     (same as above, but diskchange prompt disabled)
                           e.g.:  ramdisk=1440,no
       vga=mode

  2. The Linux kernel
       mem=number       (number = end of physical memory in bytes)
       root=device
       ro
       rw
       no387
       debug            sets console_loglevel = 10
       no-hlt           disables check of HLT isntruction at startup

  3. init
       single
       auto
       ro,rw,no387   (forwarded from the kernel)

  4. Some drivers
       reserve=port1,num1,...,port5,num5 #reserves 80x86 ioports
       ether=irq,base_addr,mem_start,mem_end,dev_name
       hd=cyl,head,sect                  # for 2 drives you need this twice
                                         # first relates to drive 0
       bmouse=irq
       max_scsi_luns=n                          # (n should be between 1 and 8)
       st0x=base_address,irq                    # SEAGATE controller ST01/ST02
       tmc8xx=base_address,irq                  # Future Domain TMC-885,TMC-950
       t128=address,irq                         # Trantor T128/T128F/T228
       ncr5380=port,irq,dma                     # Generic NCR5380 driver
       aha152x=portbase,irq,scsiid,reconnect    # Adaptec AHA-152x driver
       xd=type,irq,iobase,dma
       mcd=port,irq
       sound=0x0TTPPPID, ..
       sbpcd=sbport,SoundBlaster
       sbpcd=LMport,LaserMate
       sbpcd=SpeaFXport,SPEA


  5. Environment
       All parameters of format  name=xxxx  which are not recogized by
       the kernel or a driver are put onto the environment.

       LOADLIN itself always puts  BOOT_IMAGE=imagefile  onto the environ-
       ment.  The user may put additional values onto the environment in
       order to allow  /etc/rc  to behave differently for a given condition.


==============================================================================

Following are detailed descriptions:


Parameters recognized by LOADLIN:
=================================

  root=device
  -----------
        device     may be a symbolic device name such as "/dev/hda2"
                   or the numeric device number (hex)
                   (highbyte=major, lowbyte=minor)
                   recognized symbolic devices (with their partitions) are:
                   "hda", "hdb", "sda", "sdb", "sdc", "sdd", "sde",
                   "fd", "xda", "xdb"

        There is a problem:

        Linus interprets the number following "/dev/hda" as a HEX number,
        The device names in  /dev  of the Slackware distribution, however,
        are numbered /dev/hda1 .. hda9 .. hda10 .. hda16,
        instead of   /dev/hda1 .. hda9 .. hdaa ..  hdaf  as Linus would have done.

        So, starting with version 1.3 of LOADLIN, I interpret the root device
        myself and pass the device numerically in the boot sector.
        My naming convention is a compromise which I hope will result in
        fewer irritations:

        If the number following "/dev/hda, hdb, sda ..."
        starts with 0, 0x or a..f, it is interpreted as a HEX number.
        If it starts with 1..9 it is interpreted as a decimal number.
        If none is appropriate, the string is passed to the command line.
        (some later kernel versions may have other device names).

        Examples:
        root=302
        root=0x201
        root=/dev/hda2
        root=/dev/sdaa   same as  root=/dev/sda10  or  /dev/sda0xa

  ramdisk=size
  ------------
        size      number of Kbytes for the RAMDISK device.
                  The image for the ramdisk is loaded by the
                  kernel at startup from a floppy drive, if
                  root=/dev/fdx  is also given.
                  After loading the image, the kernel then makes
                  the ramdisk the root device (NOT the floppy).
                  In addition to this, LOADLIN prompts for inserting
                  the ramdisk image into the floppy drive if it no
                  longer needs the drive (i.e. after loading the kernel).

  vga=mode
  --------
        mode      -3  the user is asked to specify the VGA mode
                 ask  equal to -3
                  -2  80x50 extended VGA mode
            extended  equal to -2
                  -1  80x25 normal mode
              normal  equal to -1
                   0  as if "0" was entered at the boot prompt
                   .
                   .
                   n  as if the number "n" was entered at the boot prompt

  ro
  --
        "ro" forces the root device to be mounted read-only (Not for UMSDOS!)

  rw
  --
        "rw" forces the root device to be mounted read/write.

------------------------------------------------------------------------------

Parameters recognized only by the kernel:
=========================================

  mem=number
  ----------
        number     End of physical RAM, this is useful if the exact
                   installed RAM size cannot be determined automaticaly.
  root=device
  -----------
        device     May be a symbolic device name such as "/dev/hda2"
                   or the numeric device number (highbyte=major, lowbyte=minor)
                   Recognized symbolic devices (with their partitions) are:
                   "hda", "hdb", "sda", "sdb", "sdc", "sdd", "sde",
                   "fd", "xda", "xdb"
                   But NOTE: old kernels < 1.1.47 have xda=0xC00, xdb=0xC40
                             newer kernels have        xda=0xD00, xdb=0xD40
        example:
        root=302
        root=/dev/hda2


  no387
  -----
        "no387" disables use of the hardware math coprocessor.

  since 1.1.47 (or perhaps earlier) the following options are no more
  passed to init:

  ro,rw,no387
  -----------


  the following are new:


  debug  sets console_loglevel = 10
  -----

  no-hlt
  ------
         disables check of HLT instruction at startup.
         If you have a clone 486, this option is *very* usefull.

------------------------------------------------------------------------------

Option Parameters recognized by "init":
=======================================

  single
  ------
        Enter "single user mode" on boot

  auto
  ----

  ro,rw,no387
