INSTALLING OS/2: These notes cover the installation of OS/2 (versions 1.1 and 1.2) on a SCSI hard disk, using the new DISK01.SYS driver. For general OS/2 installation information, refer to your OS/2 installation guide. The first step is to use DISKCOPY to make a copy of the OS/2 installation diskette. You should then use this diskette for your OS/2 installation. Replace OS/2 1.1's DISK01.SYS file with the new DISK01.SYS file. For OS/2 1.2, which does not have a DISK01.SYS file, you will have to add new DISK01.SYS to the installation disk. There might not be enough room to do this. In this case, you will have to make room. There are two ways to do this. One is to delete a file already on the disk but which is not needed for your installation. For example, if you are not going to use the HPFS file system, you could delete HPFS.SYS from your copy of the installation diskette before trying to copy the new DISK01.SYS. Note that you should only delete files from your COPY of the installation disk. NEVER modify your original diskette. If you are using 5.25" diskettes, then another way to get extra space is to copy your 5.25" diskettes to 3.5" diskettes. 3.5" 1.44MB diskettes can hold more data, so you will have more space. To make such a copy, you should first format six 3.5" diskettes. Next, boot from the 5.25" boot diskette. Escape from the installation process when the IBM logo is displayed. At the [A:\] prompt, type the command sysinstx b: This will install the system on the 3.5" floppy. Now use the command xcopy a: b:/e/s/v to copy each of the other installation diskettes to a 3.5" diskette. After each 3.5" diskette is made, use the command label b: to give the new disk a label. Use the same label as that of the 5.25" diskette that you are copying. NOTE: If you have a primary hard disk that is not SCSI (ex: IDE or ESDI) add these two lines to your CONFIG.SYS to support SCSI drive: DEVICE = OS2CAM.SYS DEVICE = SCSIDISK.SYS
