EISA Fast SCSI Caching Adapter 6 Chapter 0 Introduction The DC-820B is an intelligent multi-tasking SCSI (Small Computer System Interface) bus to EISA bus host adapter. Up to six DC-820B adapters can be installed in one system with each adapter supporting up to seven SCSI devices.
7 EISA Fast SCSI Caching Adapter All versions of MS-DOS support two hard disk drives without adding device drivers. If MS-DOS 5.0 is used, the DC-820B BIOS can handle up to eight devices, including fixed disk and removable media, by enabling the DOS 5 Support enable/disable option during the ECU (EISA Configuration Utility) setup process.
EISA Fast SCSI Caching Adapter 8 more than one adapter co-existing in the system, then you must select which adapter you want to work with. The System has the following Host Adapter(s) 1 DC-820B HA#0 Base 330H DMA 5 IRQ 11 ID 7 2). This screen provides the information of the SCSI devices controlled by the chosen adapter (HA#0).
9 EISA Fast SCSI Caching Adapter 3) The following screen provides you the information about how many SCSI devices installed in the system and requires you to answer if to install the driver(s) or not:.
EISA Fast SCSI Caching Adapter 10 And then you go on to assign the first drive letter for the CD-ROM drive(s) used by the MSCDEX.EXE. In this case, Drive: F is reserved to the first CD-ROM drive. 4) . After confirmation, this installation program will modify both the CONFIG.

EISA Fast SCSI Caching Adapter 12 Chapter 1 HARDW ARE SETUP Before plugging the DC-820B into your system, make sure all jumpers on the card are correctly set according to instructions outlined in section 1.
13 EISA Fast SCSI Caching Adapter Warning: Do not power-down the system while this LED is still active. Doing so may result in loss of data as the contents of the cache buffer have not been completely written to the disk.
EISA Fast SCSI Caching Adapter 14 external cables, respectively. As in the above case, remove the terminators from all devices connected in between. Store the terminators in a safe place for future use, if necessary. 1.3 Cable Connection (CN1, CN2, & CN3) There are three connectors on your DC-820B: CN1, CN2, and CN3.
15 EISA Fast SCSI Caching Adapter installed, you can only install the SCSI drive with SCSI ID 0 as drive D:. If two IDE/ST506/ESDI drives already exist, no SCSI drives can be installed as C: or D:. When no IDE/ST506/ESDI drive exists, two SCSI drives with SCSI ID’s 0 and 1 can be installed as drives C: and D:, respectively.
EISA Fast SCSI Caching Adapter 16 1. Set I/O port address as 330H. 2. Set the SCSI ID as 0 and 1 for fixed disk drives. 3. Device drivers are needed for other SCSI devices, such as removable cartridge, re-writable optical disk (MO), tape streamer, DAT, and CD- ROM.
17 EISA Fast SCSI Caching Adapter 1.6.1 DC-820B Adapter Hardware Options This field allows you to select the Interrupt level, Adapter BIOS address, I/O port address, and DMA channel. Since most options in this category are Adaptec-compatible, some enhanced options will be pointed out specifically.
EISA Fast SCSI Caching Adapter 18 BIOS INT 13H. Device drivers have no effect if this Disabled option is chosen. * WARNING (if coexists with IDE HDD) * IRQ14 is used by the Primary IDE IRQ Channel & IRQ15 is used by the Secondary IDE IRQ Channel Host Adapter BIOS ADDRESS: DC000H - default.
19 EISA Fast SCSI Caching Adapter SCSI ID 7. These scanning rules apply to an environment with multiple adapters or devices. DMA Channel Definition: DMA 5 - default. This option is a pseudo- function for Adaptec compatibility. Since some software packages do require a DMA channel, there are four channels available: DMA 5/6/7/0.

EISA Fast SCSI Caching Adapter 22 F:, and so on. The following demonstrates the case of one IDE adapter with two IDE HDD drives and two DC-820Bs with seven SCSI drives.
23 EISA Fast SCSI Caching Adapter Power ON delay for SCSI devices: 30 - 120 seconds. The 30 seconds power-on delay default is applicable to most drives. Since some slower drives may fail to respond within the default power-on delay duration, you may extend this time duration in order to give sufficient time for start-up.
EISA Fast SCSI Caching Adapter 24 Cacheable device: Yes/No. This option is only valid for fixed disk, remov- able cartridge, re-writable optical disk (MO) and Floptical. The removable media device with Yes option must insert the media before the system boot- up for caching algorithm to work properly.
25 EISA Fast SCSI Caching Adapter Mirrored to SCSI ID: NO/1-7. This disk mirroring function is implemented by the DC-820B’s firmware and works for all operating systems. This option needs two and only two drives and is selected from the slave drive’s point of view .
EISA Fast SCSI Caching Adapter 26 1.7 TOOLBME.EXE Utility & Disk Mirroring Initialization TOOLBME.EXE is a utility program performing the functions of Low-Level Format, Disk Copy, Disk Compare, and Mirroring Initialization.
27 EISA Fast SCSI Caching Adapter This screen gives us the information about the adapter-0 has five SCSI devices (ID ranging from 0 to 4) and the FUJITSU M2614S/MAXTOR LXT-200S joined as a mirror pair.
EISA Fast SCSI Caching Adapter 28 always duplicates the Master Disk to the Backup Disk ( slave ). If one of the Mirror-Pair drives is malfunctioning, you can try to adjust the proper Mas- ter-Backup relation by selecting the Mirrored to SCSI ID in the ECU and then execute this module to put things in order.
