DCS AIX Installation Guide
If you do not plan on using DOS or DOS Merge then you can skip this section.
If your fixed disk is already partitioned and formatted with an operating system other than DOS as the first partition, you must back up the files on the partition(assuming you need them), and then do a "low- level format" of the fixed disk before reassigning the first partition to DOS.
If you need to "low level format" your fixed disk then follow the procedure below:
1. Place the REFERENCE DISKETTE in drive A
2. Hit enter at first display for IBM logo
3. At main menu hold the ctrl key down and press the (A) key
4. You will see the 'Advanced Diagnostic Menu', select option 2 to 'low level format' your fixed disk
The amount of time it will take to low level format your fixed disk will vary depending on the size of the fixed disk and whether or not it is a SCSI drive. SCSI drives will format in about 20 minutes or so, even for a 400meg drive. A 120 meg ESDI fixed disk will low level format in about 4 hours. A 300 meg fixed disk will low level format in about 8 hours. So, plan on a overnight low level format if you have 300 meg ESDI drive.
If you have two fixed disks and you want to use DOS and or DOS Merge with a DOS partition then make sure your primary DOS partition is on DISK #1.
Using DOS 3.3, invoke the FDISK command to create a primary DOS partition.
Follow the procedure for downloading the LPP's found in this guide and install DOS Merge.
The system responds with: Please insert your DOS 3.3 Disk into Drive A.
DOS installation is complete.
Remove the DOS disk now.
