    Installing Windows NT 4.0 (Clean) on a Fasttrak/Fasttrak66ide RAID Controller

    Installing Windows NT 4.0 (Clean) on a FastTrak/FastTrak66IDE RAID Controller * READ THIS FIRST! If you have not created any arrays using your FastTrak IDE RAID Controller, STOP and setup your array/s in the FastTrak/FastTrak66 IDE RAID Controllers Bios first before creating any Dos Partition on your boot drive, or if you plan to boot with the FastTrak/FastTrak66 like you would a Standard Hard Disk Controller create a single drive array then proceed to step #1. -Setup Procedure 1.) We STRONGLY RECOMMEND that you create a Dos Partition (no larger than 4 GB in size) before installing Windows NT 4.0 with our FastTrak IDE RAID Controller card. If possible boot up with a real dos boot disk, then execute Microsoft's FDISK to partition and format the hard disk drive. This will help to eliminate potential problems during the install process. 2.) Being the Installation process by booting up the computer with CD ROM support. Change to the CD ROM Drive letter (yours may vary) by typing "D:" (without quotations) and then pressing "enter". Then type "cd I386" and then press the "enter" key. Next type (without quotations) "winnt" or "winnt /x" (if you already have the 3 startup diskettes. After the file copying process is complete, restart your computer with the NT 4.0 boot diskette labeled "Disk1 Setup Boot disk" when prompted. 3.) Proceed with the setup process until your reach the "Mass Storage Controller auto detect screen". 4.) Next a screen will appear showing a list of Mass Storage Devices (IDE Controllers, SCSI cards, Etc.) that have been recognized by the setup program.

Patterson Computer Science Division Electrical Engineering and Computer Science Department University of California, Berkeley Berkeley, CA 94720 Abstract: We describe the implementation of a large scale disk array controller and subsystem incorporating over 100 high performance 3.5" disk chives. It is designed to provide 40 MB/s sustained performance and 40 GB capacity in three 19" racks. The array controller forms an integral part of a file server that attaches to a Gb/s local area network. The controller implements a high bandwidth interconnect between an interleaved memory, an XOR calculation engine, the network interface (HIPPI), and the disk interfaces (SCSI). The system is now functionally operational, and we are tuning its performance.

    Compaq/Conner CP341 IDE/ATA Drive

    Compaq/Conner CP341 IDE/ATA Drive 1987 Compaq/Conner CP341 IDE/ATA Drive Emergence of IDE/ATA as widely used interface. Why it's important The IDE/ATA (Integrated Drive Electronics/AT Attachment) interface, now known as PATA (Parallel ATA) and SATA (Serial ATA), became the dominant hard disk drive (HDD) interface for IBM compatible PCs, initially because of its low cost and simplicity of integration. Today it is supported by most operating systems and hardware platforms and is incorporated into several other peripheral devices in addition to HDDs. As an intelligent drive interface universally adopted on personal computers, IDE/ATA was an enabler of the acceleration of disk drive capacity that began in the early 1990s. Discussion: The IDE interface development was initially conceived by Bill Frank of Western Digital (WD) in the fall of 1984 as a means of combining the disk controller and disk drive electronics, while maintaining compatibility with the AT and XT controller attachments to a PC without changes to the BIOS or drivers. WD floated that idea by its largest customers, IBM, DEC, and Compaq in the winter and spring of 1985. Compaq showed interest, so Bill Frank collaborated with Ralph Perry and Ken Bush of Compaq to develop the initial specification. WD formed a Tiger team in the spring of 1985 to build such a drive, using externally purchased 3.5” HDAs (Head Disk Assemblies), but initially just provided IDE to ST506 controller boards that Compaq hard-mounted to 10MB and 20MB 3.5” Miniscribe ST506 drives for their Portable II computer line, announced in February 1986 [3, 15, 20].
