BusLogic LADDR Support for IBM OS/2 1.3 --------------------------------------- This installation note outlines the steps needed to install BusLogic's OS/2 1.3 LADDR device driver under IBM OS/2 version 1.3. The installation procedure will "ladderize" the IBM OS/2 system. Ladderizing replaces the original IO subsystem on your OS/2 Install diskette or OS/2 installed system with a LADDR IO subsystem. The first section discusses installing the BusLogic driver at the time of initial OS/2 1.3 installation. The following sections discuss adding the BusLogic driver (and host adapter(s)) to an existing OS/2 1.3 system. In this case, (called a secondary installation) remember to: *** Make a complete backup of your boot volume *** before attempting to ladderize. I. BusLogic SCSI Host Adapter as Intended Boot Adapter This set of instructions assumes NO existing OS/2 1.3 system. It assumes you are doing an initial installation of OS/2 1.3 onto a disk supported by a BusLogic SCSI host adapter. o Backup (Diskcopy) the OS/2 installation disk - it will be modified during this procedure. o Boot the backup copy installation disk. o At the first full screen when asked: "Enter to continue Or Escape to Exit" hit Escape. o After the A:\ prompt appears, remove the installation disk. o Insert the BusLogic SW-190 installation disk. o Type: A: <enter> CD \OS213\IBM <enter> o Determine the location of the ram disk created by the IBM install disk in the following manner: Type: DIR X: <enter> where X is a drive letter ,starting with C and continuing with ascending drive letters (i.e., C,D,E,...) UNTIL the following message appears: SYS0015: The system cannot find the drive specified. The ram disk is the drive letter immediately BEFORE the current drive letter value. Examples: If DIR D: is the first drive letter to produce the error message above, then the ram disk is drive C:. If DIR E: is the first drive letter to produce the error message above, then the ram disk is drive D:. o For Microchannel installations, type: GO drive: MCA <enter> where drive is the ram disk drive letter identified in the step above. For ISA and EISA installations, type: GO drive: ISA <enter> where drive is the ram disk drive letter identified in the step above. o When prompted to, remove the BusLogic SW-190 install disk and insert the OS/2 installation disk. The OS/2 installation disk will now be modified. Use this modified installation diskette for the rest of the installation. o Reboot the machine. o Continue as instructed with the installation. o At the very end of the normal system installation, when the message "Remove the floppy from drive A:" appears, reinsert the modified installation diskette. o Reboot the machine. o At the first full screen when asked: "Enter to continue Or Escape to Exit" o hit Escape. o Type: HARD.cmd <enter> This program copies the proper files to the hard disk. Failure to complete this step will result in a TRAP when attempting to boot from the hard disk. o Ladderized Installation is now Complete ! Reboot the machine. II. BusLogic MCA SCSI host adapter as Secondary (non-boot) Device This set of instructions assume an existing OS/2 1.3 system to which you wish to add one or more BusLogic MicroChannel SCSI host adapters. WARNING!!! Back up the existing system before continuing to the next step! o Under OS/2, create an OS2 command window. o Insert the BusLogic 1.30 driver install disk in drive A: o Type: A: <enter> CD \OS213\IBM\IBM_130.MCA <enter> SECONDAR <enter> o Ladderized Installation is now Complete ! Reboot the machine. III. BusLogic ISA or EISA SCSI host adapter as Secondary (non-boot) Device This set of instructions assume an existing OS/2 1.3 system to which you wish to add one or more BusLogic ISA or EISA SCSI host adapters. WARNING!!! Back up the existing system before continuing to the next step! o Under OS/2, create an OS2 command window. o Insert the BusLogic 1.30 driver install disk in drive A: o Type: A: <enter> CD \OS213\IBM\IBM_130.ISA <enter> SECONDAR <enter> o Ladderized Installation is now Complete ! Reboot the machine. IV. Adding CDROM support o Install as described above. o Insert the BusLogic SW-190 install disk in drive A: o Type: MD C:\CDROM <enter> o Type: A: CD \OS213\IBM\CDROM <enter> COPY A:*.* C:\CDROM <enter> o Edit config.sys - Insert the following three lines starting at the first line of the file (or second line if the first line is "IFS=C:\OS2\HPFS.IFS /cache:64"): IFS=C:\CDROM\CDFS.IFS DEVICE=C:\CDROM\STDCDROM.VSD DEVICE=C:\CDROM\CDROM.TSD o Exit your editor and type: COPY C:\CDROM\UCDFS.DLL to C:\OS2\DLL <enter>Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
