/uussrr/ssyyss/BBuuiilldd _o_p_t_i_o_n__l_i_s_t

The script  /uussrr/ssyyss/BBuuiilldd builds a new COHERENT  kernel.  Its many options
allow you to choose the mix  of devices to linked into the new kernel.  The
following describes these options in detail.

aall, aassyy, hhss
          The default  device driver for  async devices is  aassyy. You _c_a_n_n_o_t
          combine  this device  with either of  the older  (i.e., obsolete)
          drivers aall or  hhss. However, aall and hhss may  both be present in the
          same kernel.  If you include aall or hhss, you must create the proper
          device nodes in directory /ddeevv.

aahhaa, aatt, ssss
          The default driver is aatt only, for a system with an AT-type (MFM,
          RLL, ESDI,  or IDE)  hard drive.   You can use  any one  of these
          devices in  a configuration, and  you can use  aatt and one  of the
          SCSI  devices in  the same  kernel.  You  cannot patch  both SCSI
          devices, aahhaa and ssss, into the same kernel.

kkbb, kkbb_dd, kkbb_ff, nnkkbb
          You can  use only  one of  these keyboard drivers.   nnkkbb supports
          keyboard tables,  which you  can load  with the commands  kept in
          directory  /ccoonnff/kkbbdd). It  uses scan-code set  3, which  does not
          work on about 5% of the cheap clone keyboards.

          Driver kkbb  works on  all keyboards,  but does not  allow loadable
          keyboard  configuration and is  therefore for  U.S.-style systems
          only.

          Drivers kkbb_dd  and kkbb_ff are,  respectively, the German  and French
          variants of the kkbb driver.

vvtt        Use this option to support virtual consoles.  Because this driver
          uses  an  extension  of the  nnkkbb  keyboard  driver,  none of  the
          previous  keyboard  drivers should  be  specified,  and the  same
          keyboard restrictions apply to vvtt as to nnkkbb above.

vvttkkbb, vvttkkbb_dd, vvttkkbb_ff
          You  can use  only one  of these  keyboard drivers.   Driver vvttkkbb
          works  on all  keyboards, but  does  not allow  loadable keyboard
          configuration and is therefore for U.S.-style systems only.

          Drivers  vvttkkbb_dd  and vvttkkbb_ff  are,  respectively,  the German  and
          French variants of the vvttkkbb driver.

-aa _a_s_y_n_c-_f_i_l_e
          If you use device driver aassyy,  this option lets you supply a file
          other  than  /eettcc/ddeeffaauulltt/aassyynncc  as  the  option to  the  command
          aassyyppaattcchh.

-cc _c_o_m_p_i_l_e_r-_f_l_a_g_s
          This option lets you pass compiler flags directly to mmaakkee.

-iipp       This option tells BBuuiilldd to repeat  the same set of patches on the
          new  kernel that  you patched  into the  present kernel  when you
          installed COHERENT  on your system,  before it patches  in any of
          the requests you are making now.

-oo _k_e_r_n_e_l-_f_i_l_e:
          Name the kernel file to be  created.  If you are booting from the
          hard  drive,  the  kernel  file  must  be  located  in  the  root
          directory.

_X=_Y       If  an option  string  contains an  equal sign,  BBuuiilldd passes  it
          directly as an argument  to command ppaattcchh, which is applied after
          the kernel is built.

_E_x_a_m_p_l_e_s
For example, an invocation of:

    Build at nkb

builds  a  COHERENT  kernel using  the  aatt  device  driver  for the  AT/IDE
interface hard disk, using device driver nnkkbb which is the user configurable
keyboard device driver.

An alternate configuration could be:

    Build -ip ss kb

which builds a  COHERENT kernel using the ssss device  driver for the Seagate
and Future Domain SCSI interface hard disk, using device driver kkbb which is
the traditional COHERENT  keyboard device driver.  The kernel file produced
will be  patched the same as  the current kernel on  the host system.  _N_o_t_e
