The following tips were retrieved from the Micropolis BBS as tech tips which their support team uses in resolving customer issues. 1. Ultrastor 12F when installing NETWARE 2.15A Low-level format using the physical parameters(no translation) to use the full capacity of Micropolis drives that exceed 1024 cylinders. Install Advanced Netware 2.15A using the "Default" configuration. 2. Ultrastor 12F in EISA machines. To configure an Ultrastor 12F in an EISA bus you must use the file USC0120.CFG located on the ultrastor diskettes. 3. WD1007x Say "NO" to "enable alternate sectors?" during low-level the format. The use of alternate sectors will disable WD1007x 63 sector translation mode. *NOTE* alternate sectors may be enabled when no translation will be required. 4. WD1007v-SE1/SE2 Models 1568-15 and 1664-7 must have the W2 jumper removed from the drive. Removing the W2 jumpers changes the drive geometry from 54 to 53 spt. The WD1007V does NOT support 54 spt. 5. SCSI The drive and host adapter must have different SCSI ID's. Conflicting SCSI ID's will cause a variety of problems. 6. ESDI Drive Splitting Enabling drive splitting with ESDI controllers will limit the system to one physical EDSI drive. The computer CMOS must be set for two physical drives set to type (Type 1) 7. ESDI When using ESDI controllers and drives, you must be sure that the controller has a transfer rate equal to or higher than the drive. Eg.. WD1007A is a 10 Megahertz controller, with a 1664- 7 which is a 15 Megahertz drive. This is an incompatible mix. 8. UltraStor and Netware UltraStor 12/f is certified for Netware 2.2 and Netware 386 v3.11 with the Rev 009 bios on the controller. 9. In-2000 Synchronous negotiation Set SW-8 to "ON" position to force the IN-2000 to initiate synchronous negotiation. 10. HS Code HS code supports 512 bytes per sector only. This applies to firmware P/N 800574-XX-X. 11. RS6000 HSP4 (800574-03-0) will issue an Illegal request in CDB(05/24h) when formatted with AIX "Service and Diagnostics Module". ASOC must be used in an IBM RS6000 machines. HS code doesn't support a command issued by the RS6000. 12. Future Domain 1680 Host Adapter Disk Manager will not initialize a drive over 1.2 gigabytes. You must use have a bios revision of 2.0 and higher for the Future Domain 1680. You must use Disk Maestro or Debug to format the drives. 13. SCO UNIX The boot partition must reside under 1024 cylinders or you will have erratic behavior of the OS. 14. Ultra 12f-24 with Two drives When a 1518-15 is attached to the 12f and additional drive will be will be added , the bios on the Ultrastor should be Rev. -010. 15. DPT / MYLEX WITH 1598 AND 1528 The firmware on the drives must be DD24_1 to work with DPT and Mylex Host Adapters. 16. PS2 Model 95 and 1528 Configure automatically with the reference diskette and the utility will return '????' as the 2nd drive. After configuration, the drive will respond normally. 17. Always and UNIX / XENIX If a customer has problems creating the N1 boot diskette, the customer can call Always and they will create the N1 diskette for the customer. 18. WESTERN DIGITAL 7000FASST The WD7000FASST host adapter does not support parity. Micropolis drives must have parity disabled by placing a jumper on W9 on the 1674 /1684 or w4 on 1578/1588/1598/1528. On the models 1548/1908/1624 drives to disable parity jumper in 13-14 in the J2 connector. (Download the drive spec sheet from the files section of the BBS). 19. ULTRASTOR(ALL CONTROLLERS) Ultrasor ESDI controllers will not co-reside with any other manufacturers controller card under Netware.
