Page 7: Getting Started
1. Getting Started This manual contains the information you will need to install and use the EXM-9 disk controller. The EXM-9 disk controller allows you to use external floppy disk and IDE (integrated device electronics) hard disk devices. It is designed to plug into any slot in an EXMbus carrier. -

Page 9: Installation
FREE ENVIRONMENT Insertion in an EXM Carrier Once the header pins are set, insertion of the EXM-9 into an EXM carrier is straightforward. Remove a blank EXM panel from the carrier (by unscrewing the thumbscrews) and insert the EXM-9 into the card guides. -
Page 10: Configuring The Bios Setup
EXM-9 Hardware Reference Configuring the BIOS Setup Once the EXM-9 is inserted into the carrier, turn the system on and boot it up. The EXM configuration data in the EPC to which the EXM-9 is connected now must be modified to recognize and enable the card and select from the available options. -

Page 13: Operation
3. Operation This chapter discusses the main setup and connectors of the EXM-9. In addition to configuring the EXM-9 using the EXM Setup Screen, you will also need to describe your connected disk configuration on the main setup screen. If you have a floppy drive connected and enabled, select the diskette drive A option that matches your floppy drive. - Page 14 EXM-9 Hardware Reference 2. For use by the translation mapping, select either 63 or 17 sectors per logical track. Call this value S. Use S of 63 for drives greater than 136 MB, and S of 17 for smaller drives.

Page 19: Programming Interface
4. Programming Interface This chapter contains information needed to write custom software drivers for the EXM-9. Anyone just using the EXM-9 as a BIOS-controlled interface to external disks can skip reading this chapter. The EXM-9 defines the following registers in the I/O space. - Page 20 The first two are standard EXM registers for device identification and configuration. The EXM-9 responds to accesses to these ports only if EXMbus line -EXMID is asserted. An 8-bit read from I/O address 100h returns the value F6, the device ID of the EXM-9.
- Page 21 IDE drive. Note that both the IDE interface and the floppy controller use address 3F7. Because of this, you cannot build a system containing an EXM-9 where the floppy controller function is being handled by some other device (e.g., another EXM-9, an EXM-3, an EXP-MS/MX);...
