Installing SCO OpenServer 5.04 on FT2400 MB440LX (Nexus) Product

 Installation with the on-board Symbios controllers

The following instructions are for installing SCO OpenServer 5.04 onto the FT2400 Nexus machine using the on-board Symbios 82C875 controller

Step 1 - To install SCO OpenServer 5.04 you will need to create 2 floppy disk images.

  1. Symbios SCO UNIX drivers disk
  2. Nexus replacement boot floppy

Both the disk images can be found in area39 of the Apricot Insight Online BBS/Web site at www.apricot.co.uk/ftp/bbs/area39.
The Symbios diskette image is stored both as "SYMB_SCO.z" (a UNIX compressed dd disk image) and as "SYMB_SCO.DSK" (dd disk image).
Note that there is no functional difference between them – download whichever one is more convenient to use.
The replacement boot floppy is called "BOOT2400.DSK" (dd disk image)

Don’t forget that a disk image file (.DSK) can be downloaded onto a DOS machine, and written straight to a floppy diskette, using the RAWRITE.EXE programme (also in file area 39 of the bbs).

The Symbios drivers disk can also be found on the FT2400 bootable CD-ROM – follow the menu options for creating driver disks if you prefer this method.

Step 2 - Boot the machine from the "Nexus boot floppy"

The SCO Openserver Boot: prompt will be displayed, at this point, type the following boot string :

defbootstr Sdsk=slha(1,0,0,0) Srom=wd(0,0,0,0) disable=alad

note : the 1 in the Sdsk=slha signifies the SCSI channel A on the Symbios ultra wide controller, 2 can be used for channel B

Step 3 - You will now be asked which media device you wish to install the product from, select the following :

Media device to be used : IDE CD ROM
IDE Controller : primary
Master or Slave : master

  • The files will now be extracted from the CD ROM drive and the installation will proceed as normal.

Step 4 - When the operating system is installed reboot the system from the Nexus boot floppy and enter the following boot string at the Boot : prompt

fd(64)unix swap=hd(41) dump=hd(42) disable=alad Sdsk=slha(1,0,0,0)

Step 5 - When the system has completed its boot sequence, login as root and run the installpkg command from the root shell.

Insert the Symbios drivers disk created earlier, and select the replace option to replace the slha driver.

You will now need to rebuild the UNIX kernel, as follows :

# cd /etc/conf/cf.d
# ./link_unix

Step 6 - Boot the server as normal, the installation process is now complete

Installation with the AMI434 Raid Controller

The following instructions are for installing SCO OpenServer 5.04 onto the FT2400 Nexus machine using the AMI434 RAID Controller

Step 1 Create the AMI MegaRaid drivers disk from the Drivers CD

Step 2 - Boot the machine from the "OpenServer 5.04 Boot Floppy"

The SCO Openserver Boot: prompt will be displayed, at this point, type the following boot string :

defbootstr ahslink=amird Sdsk=amird(0,0,0,0) Srom=wd(0,0,0,0) disable=alad disable=slha

You will be prompted for the AMI drivers disk you created in Step 1 during this stage.

Step 2 - You will now be asked which media device you wish to install the product from, select the following :

Media device to be used : IDE CD ROM
IDE Controller : primary
Master or Slave : master

The files will now be extracted from the CD ROM drive and the installation will proceed as normal.
