                   SiS IDE Driver Installation For DOS
                  =====================================

01) Run INSTALL.EXE in the install utility diskette to install
    SiS IDE DOS PIO mode driver or SiS IDE DMA mode driver.

02) INSTALL.EXE program will add the following line in CONFIG.SYS file :
         "DEVICE=C:\SISIDE\SISDR.SYS"    for PIO mode driver or
         "DEVICE=C:\SISIDE\SISDR.SYS /M" for DMA mode driver.

03) Users can use /A /R parameters to set the wait states and
    IDE BUS MASTER  CONFIGURATION SPACE BASE ADDRESS manually.
    For example:
        "DEVICE=C:\SISIDE\SISDR.SYS /A3456 /R6543"
         means active time for channel 0 master is 3*30ns
                               channel 0 slave  is 4*30ns
                               channel 1 master is 5*30ns
                               channel 1 slave  is 6*30ns

         recovery   time   for channel 0 master is 6*30ns
                               channel 0 slave  is 5*30ns
                               channel 1 master is 4*30ns
                               channel 1 slave  is 3*30ns

04) Hard Drives' default wait states are set by using Hard Drive
    internal information automatically. The recommended value table
    for different mode Hard Drives is as follow :

         Hard Disk Mode    4       3       2      1      0
         ==================================================
         Recovery Time     1       3       8      A      0
         Active Time       3       3       6      6      0
         ==================================================
         Note that the range for Recovery Time is 0-F
                         and for  Active  Time is 0-7.

05) After IDE DOS driver installed. Some mode 4 hard disks may cause the
    system hang when we reboot the system. Users can avoid this by downing
    the speed in manual way as described in 03) 04).
    For example, change
         "DEVICE=C:\SISIDE\SISDR.SYS" into
         "DEVICE=C:\SISIDE\SISDR.SYS /A3 /R3"
