ST1102A INSTALLATION !WARNING! - DO NOT LOW-LEVEL FORMAT OR INITIALIZE THE ST1102A DRIVE. DOING SO WILL DELETE IMPORTANT FACTORY-WRITTEN DEFECT INFORMATION. THE ST1102A HAS ALREADY BEEN INITIALIZED AT THE FACTORY. --------------------------------------------------------- Pure DOS installation for the ST1102A: If your system has an exact match to this drive, it will show 1024 cylinder, 10 heads and 17 sectors per track. Some BIOS' actually do support this configuration as a standard drive type. If the drive is not directly supported, then check to see if your system has the capability of a "Custom" or "User Definable" CMOS drive type (often type 47), set it up as 1024 cyls, 10 heads, 1024 reduced write current, 1024 write precompensation cylinder, 1024 landing zone (drive is AutoPark), and 17 sector per track (89,128,960 bytes). 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 exact match or "User Definable" drive type, and you wish to maintain a pure DOS environment, your choices are limited to selecting drive type 35 (1024-9-17 = 80,216,064 bytes), or type 37 (830-10-17 = 72,243,200 bytes), or type 12 (855-7-17 = 52,093,440 bytes), or getting a BIOS upgrade with either direct support for the drive or with "User Definable" drive types. ======================================================== ======================================================== DISK MANAGER V4.0 or above INSTALLATION FOR THE ST1102A: The DISK MANAGER preparation software may be used to get the full capacity (89,128,960 bytes) from the drive as a NONSTANDARD drive not supported by the BIOS drive type table. 1. In the CMOS setup, select drive type 37 (830 cylinders, 10 heads, and 17 sectors per track = 72,242,200 bytes) which is common for most BIOS's. (If your BIOS is older and does not include a common type 37 , an alternate method using drive type 12 is described at the end of this document). 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 829 cyls, 10 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 72,242,200 bytes. The ST1102A 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 ST1102A should look like this: 1024,10,1024,1024,0,8,0,0,0,1024,17,1 This configuration yields 89,128,960 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 ST1102A, 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 1024 cyls, 10 heads and 17 sectors. From the main menu select (C)onfiguration menu and then (W)rite configuration record to disk. The screen should say something like " Drive 1 is 829 by 10 by 17 and is actually 1023 by 10 by 17". (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 193 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 193 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. 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 ST1102A. ============================================================== What to do if your system does not have a type 37: You MUST have Disk Manager V4.03. If type 37 is not available, the installation can be accomplished using drive type 12 (855-7-17 = 52,093,440 bytes). Continue with steps 2-14 but instead, the PARM1.FIL should read: 1462,7,1463,1463,0,8,0,0,0,1463,17,1 Keep in mind that the number of megabytes available on the first run-through with disk manager will equal the capacity of drive type 12. After the PARM1.FIL is in place and Disk Manager is started again, during (W)rite configuration record to disk the screen should look like "Drive 1 is 854 by 7 by 17 and is actually 1461 by 7 by 17". ============================================================== Quick reminder: DISK MANAGER is licensed software, and each copy has a unique serial number.
