OS-9 V2.4 on EUROCOM-17 1 Getting Started 1 Getting Started This manual contains informations about the implementation dependent part of OS-9/68K ELTEC systems. We recommend, that you are familiar with the following documentations: •EUROCOM-17 Hardware Manual •RMon Manual •OS-9/68K Users Manual •Using UMACS 1.1 Pre-Installed System If you have ordered a complete system, the operating system will already be installed completely on the harddisk, when shipped off.
1 Getting Started OS-9 V2.4 on EUROCOM-17 If you want to use a VGA monitor and MF-2 keyboard, set hex switch S2 to '0'. Connect the floppy drive(s) and harddisk(s) according to the description in the hardware manual and jumper them as mentioned in Section 4.2 ‘Fixed Device Parameters’of this manual. Now switch on the terminal and the EUROCOM-17. The LED display now indicates 'F', and you should get the power-on message of the RMon monitor from the terminal.
OS-9 V2.4 on EUROCOM-17 2 Installing OS-9 V2.4.5 2 Installing OS-9 V2.4.5 This chapter explains the installation of the new OS-9 release on a harddisk. 2.1 Booting from Floppy Disk After power-up, the EUROCOM-17 prompts with its monitor program. All commands described in the RMon manual are ready to be used. Insert disk labeled ‘OS9 Bootdisk’into drive 0 if you wish to boot from floppy.
2 Installing OS-9 V2.4.5 OS-9 V2.4 on EUROCOM-17 Type 'c' to change boot controller. "Controller: TEAC" Press '' to select SCFL as boot device. Press '' to accept. 3. Type 'x' to exit boot menu. 4. Type 'x' to exit setup menu. "Save parameters (y/n)?" Type 'y' to save the selected parameters. "[***]>" 5. Type 'boot' to boot OS-9/68K. 6. The boot device is selected and the operating system comes up.
OS-9 V2.4 on EUROCOM-17 2 Installing OS-9 V2.4.5 2.2 Installing OS-9 V2.4.5 on an Empty Harddisk It is recommended to install the operating system on a fresh formatted harddisk. Boot the system from floppy, load the appropriate harddisk descriptor and format the harddisk (see Section 2.1 ‘Booting from Floppy Disk’). 1. Load the back utility from your boot disk and change the current directory to harddisk. $ load back $ chd /h0 2.
2 Installing OS-9 V2.4.5 OS-9 V2.4 on EUROCOM-17 2.3 Updating OS-9 V2.X to V2.4.5 Installing the software on a harddisk already containing an OS-9 (older version or version for a different CPU) may cause trouble if modules are mixed between different releases. The following procedure is a save way to avoid this: 0. Make a complete backup of the harddisk. 1. Generate a bootable floppy with the old version of the operating system. 2.
OS-9 V2.4 on EUROCOM-17 2 Installing OS-9 V2.4.5 4. Generate a new boot file on the harddisk with os9gen . Examine the sample bootlist file in CMDS/BOOTOBJS and add the necessary drivers and descriptors. For the information which drivers and descriptors are needed, refer to Chapter 3 ‘Drivers and Descriptors’. $ chd /h0/cmds/bootobjs $ dmode /h0 format=on $ os9gen /h0 -z=bootlist -eb=200 i The harddisk descriptor may have the Format Inhibit bit set.
2 Installing OS-9 V2.4.5 2.4.2 OS-9 Configuration without SSM OS-9 V2.4 on EUROCOM-17 ELTEC supplies two modified syscache040 modules, which configure the address space of the EUROCOM-17 as follows: syscache040.cb $0000.0000 - $01FF.FFFF: both caches enabled, copy back mode $0200.0000 - $FDFF.FFFF: both caches enabled, write through mode $FE00.0000 - $FFFF.FFFF: both caches disabled, all serialized syscache040.wt $0000.0000 - $01FF.FFFF: both caches enabled, write through mode $0200.0000 - $FDFF.
OS-9 V2.4 on EUROCOM-17 2.4.4 Notes and Restrictions 2 Installing OS-9 V2.4.5 The DDIO bit in module init is set by default. This tells the kernel not to disable the data cache when in I/O. Disabling data cache is required for systems with drivers which use DMA and don't perform any explicit data cache flushing. If your system does not use DMA drivers, or the drivers care for the cache, the DDIO bit should be set. The DDIO bit has to be modify by the label NoDataDis in systype.d .
2 Installing OS-9 V2.4.5 OS-9 V2.4 on EUROCOM-17 2.5 Floating Point Support This release provides soft- and hardware floating point instructions. The following instructions are supported by software: facos , fasin , fatan , fetox , fint , fintrz , flog10 , flogn , fmovecr , fsin , fcos , ftan and ftentox .
OS-9 V2.4 on EUROCOM-17 2 Installing OS-9 V2.4.5 2.6 Memory Configuration with MemList The memory size is set to 2 MB per default with UsrMemEnd label in DEFS/systype.d . If a EUROCOM-17 with a different memory size is used, modify the memory list or choose one of the uncommented UsrMemEnd samples in DEFS/ systype.d . Set the 2 MB UsrMemEnd to comment and remove the comment for your configuration. Init.a contains the following MemList: MemList * Select one of predefined UsrMemEnd labels in systype.

OS-9 V2.4 on EUROCOM-17 3 Drivers and Descriptors 3 Drivers and Descriptors This chapter describes the drivers and descriptors for clock, RBF, SCF and SBF type devices. All these modules are in directory CMDS/BOOTOBJS. Your directory may contain more drivers and descriptors as mentioned here, since ELTEC feels free to add devices as they become ready, without changing the documentation. 3.
3 Drivers and Descriptors OS-9 V2.4 on EUROCOM-17 3.2 RBF Drivers The RBF drivers are structured in a physical and logical part. • scsi17 is the physical driver which deals the NCR53C720 SCSI I/O controller and has to be loaded if any SCSI I/O is desired. • rbvccs / rbcvccs is the logical driver for all harddisks with embedded SCSI controller. • rbteac / rbcteac is the logical driver for TEAC FC-1 floppy disk with integrated SCSI controller.
OS-9 V2.4 on EUROCOM-17 3 Drivers and Descriptors 3.3 RBF Descriptors The source of these descriptors is located in the IO/RBF directory. 3.3.1 Descriptors for Harddisk with embedded SCSI All descriptors for embedded SCSI disk have the logical unit number (LUN) 0. h0.embscsi h0.scsi256 h0.scsi512 dd.h0.embscsi The descriptors refer to SCSI ID 6. h1.embscsi h1.scsi256 h1.scsi512 dd.h1.embscsi The h1 descriptors refer to SCSI ID 5. h2.embscsi h2.scsi256 h2.scsi512 dd.h2.

The sc17cons displays 24 lines of 80 ASCII characters per line (default setting), with scrolling, (x, y) cursor addressability, and some other control functions. The non-blinking block cursor marks the current line and character position on the screen.
Appendix A: Control Sequence Codes [ CSI OS-9 V2.4 on EUROCOM-17 represents the ASCII escape character (, -[, $1B). The next character is a left square bracket '[' ($5B). are a sequence of zero or more decimal numbers made up of digits between 0 and 9, separated by semicolons. represents a function character which is different for each control sequence. represents the ANSI control sequence introducer ($9B).
OS-9 V2.4 on EUROCOM-17 Appendix A: Control Sequence Codes If a syntactical error is found within a sequence, the sc17cons output function skips all input until a terminating code is encountered, which results in a return to the normal not-in-sequence state. • [ A Cursor Up (CUU) Takes one parameter, (default 1). Moves the cursor up lines. If the cursor is fewer than lines from the top of the screen, moves the cursor to the topmost line on the screen.

The portion of the screen from the current line inclusive to the bottom is scrolled upwards by lines. The new lines scrolling onto the bottom of the screen are filled with spaces. The old lines beginning at the cursor line are deleted. The position of the cursor on the screen is unchanged.
