ST1144A INSTALLATION !WARNING! - DO NOT LOW-LEVEL FORMAT OR INITIALIZE THE ST1144A DRIVE. DOING SO WILL DELETE IMPORTANT FACTORY-WRITTEN DEFECT INFORMATION. THE ST1144A HAS ALREADY BEEN INITIALIZED AT THE FACTORY. --------------------------------------------------------- Pure DOS installation for the ST1144A: If your system has the capability of a "Custom" or "User Definable" CMOS drive type (often type 47), set it up as 1001 cyls, 15 heads, 1002 reduced write current, 1002 write precompensation cylinder, 1002 landing zone (drive is AutoPark), and 17 sector per track. Then go straight to the DOS utility FDISK to partition the drive, and finish the installation with the DOS FORMAT command. See you DOS manual for instructions for FDISK and FORMAT. If your system does not have the "User Definable" drive type, and you wish to maintain a pure DOS environment, your choices are limited to selecting drive type 9 (117,504,000 bytes), drive type 41 (119,723,520 bytes), or getting a BIOS upgrade with either direct support for the drive or with "User Definable" drive types. ======================================================== ======================================================== DISK MANAGER INSTALLATION FOR THE ST1144A: The DISK MANAGER preparation software may be used to get the full capacity (130,690,560 bytes) from the drive as a NONSTANDARD drive not supported by the BIOS drive type table. 1. In the CMOS setup, select drive type 9 (900 cylinders, 15 heads, and 17 sectors per track = 117,504,000 bytes) which is common for most BIOS's. 2. Using a bootable floppy diskette, boot to the A: drive. 3. Start the Disk Manager program in the MANUAL MODE by typing at the A: prompt DM/M. 4. At the top of the screen, you should see the parameters from the CMOS setup as 899 cyls, 15 heads and 17 sectors (one of the cylinders is always given away as the CE or Customer Engineering cylinder for read/write tests). 5. From the main menu, select (P)artitioning menu and proceed to build a (N)ew partition table. The first partition is a DOS bootable and any others are Write/Read. After all cylinders are allocated, save the partition record and Prepare all DOS/Write-Read partitions. Disk Manager will ask for you to place the bootable DOS diskette is drive A: when the time comes to copy the system files and command.com to the root directory of the C: drive. When the preparation of all the partitions is completed, there will also be a CONFIG.SYS file (with device = DMDRVR.BIN) and a driver file called DMDRVR.BIN in the root directory of the C: drive. 6. The system should now boot, load the DMDRVR.BIN and display the Disk Manager banner, and come to the C: prompt. The total number of megabytes is equal to the CMOS drive type definition of 117,504,000 bytes. The ST1144A can be brought up to full capacity by the creation of an auxiliary file called PARM1.FIL. 7. Modify the CONFIG.SYS file: from: device = dmdrvr.bin to: device = dmdrvr.bin parm1.fil parm2.fil PARM1.FIL and PARM2.FIL are DRIVE PARAMETER FILES. Create with the "COPY CON PARM1.FIL" command. The contents of the PARM1.FIL for the ST1144A should look like this: 1001,15,1002,1002,0,8,0,0,0,1002,17,1 This configuration yields 130,690,560 bytes. If you use the COPY CON command, use a ^Z (control-Z) to close and save the file. These 2 files must, of course, exist on the boot device. Also, note that if you have only a 1 drive system, the "device =" statement in CONFIG.SYS still must contain 2 file names. They may, however, both be the same filename: device = dmdrvr.bin parm1.fil parm1.fil 8. Now that the PARM1.FIL has been created containing the parameters for the ST1144A, and the CONFIG.SYS file has been modified, the system is ready to be rebooted. 9. Switch over to the A: drive and start the Disk Manager program in the MANUAL MODE by typing at the A: prompt DM/M. 10. At the top of the screen, you should see the parameters from the device driver as 1000 cyls, 15 heads and 17 sectors. From the main menu select (C)onfiguration menu and then (W)rite configuration record to disk. (R)eturn to the main menu. 11. From the main menu, select (P)artitioning menu and proceed to (M)odify the partition table. The partition record should look the same as before with the addition of 100 more cylinders left to (A)llocate as a Write/Read partition. The first partition is a DOS bootable and any others are Write/Read. After the last 100 cylinders are allocated, save the partition record and Prepare all newly allocated partitions. Note: You could also change partitioning information by deleting the existing Write/Read partitions (NOT the DOS partition), from last to first, and then recreating the partition structure sequentially, first to last. Then save the partition record and Prepare all newly allocated Write/Read partitions. It is a good idea to do a Printscreen of the partitioning table. 12. The system should now boot, load the DMDRVR.BIN PARM1.FIL and display the Disk Manager banner, and come to the C: prompt with full capacity for the ST1144A. ============================================================== Quick reminder: DISK MANAGER is licensed software, and each copy has a unique serial number.
