Installing the |RMX ll Software

This step explains how to install the iRMX II software from cartridgc tapc to your system's hard disk. This step execures a SUBMIT file that performs all of the steps of installing the iRMX II files to your hard disk.

Two installation oDtions are orovided:

Option Action

A. Format your miclocomputer's entire hard disk

B. Format only Track 0 of the hard disk with the second stage of the iRMX II Bootstrap Loader

In ùe description of each option, you will read reasons for selecting that option. Betbre executing either option, insert the tape cartridge into the drive.

To do this, first remove the tape from the protective box. Next, gasp the tape cartridge by the end nea.est the write-protect switch (labe ed',SAFE,). Insert the tape into the tape drive with the write-protect switch nea.est the drive's door handle. Push the tape cartridge in until it shifts slightly and does not eject when you release it. Move the drive's door handle toward the tape to the locked position.

OPTION A: Formanlng Your Microcompuîer's Entire Hard Disk Drive

You should choose this option if:

r You have a new mic.ocomputer system that has nothing on the hard disk. A1l new Intel systems are shipped with unformatted (empty) hard disks.

. You wish to use the RESERVE feature of the Human Interface FORMAT command.

This feature is used to create a copy of the maps that the iRMX II Operating System's uses to find keep track of your data. This copy is used if the working copy becomes corrupted. CoÍuption of a computer's file structure can be caused by power failure or other equipment failures.

The Intel-supplied SUBMII file that you execute to format a hard disk automatically sp€cifies the RESER\E feature. Refer to the Opemtor's Guida To The Extended

|RMX II Hurnlin Intelace manual for details on the RESERVE feature of the FORMAT command.

. You have already backed up this disk and want to rebuild your file structure. The p.ocess of backing up your files, formatting the disk, and then restoring your iiles will improve the disk's file structure, which can become fragmented during normal usage.

FraSrneotation oscurs whcn filcs are deleted, freeing space on various sectors;

subsequently, when new files are created, this ftee space is used by placing parts of new files in them. This can cause the disk to spend a large amount of timc secking to the location where the next oart of a iile is located.

Step 1 of the Software Installation process contains information on hov/ to backup your system.

The follolvhg Intel-supplied SUBMIT commands will format the entire hard disk. T)?e in the following command using Tables 3-1, 3-2, and 3-3 to fill in the three paramete$.

using. Refer to Table 3- 1 for the appropriate interleave value.

is the maximum number of files yoù want to be able to create on your hard disk. This number depends on your application. A good rule ofthumb is, if the microcomputer is to be used for

development pùrposes, speciry 125 files per megabyte ofyour hard disk's capacity. Thus, a 40 M-blte hard disk can reasonably be formatted to contain 5000 files. However. if the number of files

nccris to be changed later, you will havc to backup your files and

reformat your hard disk.

Examplcs of Option A, FormattinS the Entire Hard Disk

Remember! You must insert the certridge tepe before invoking this commend.

A valid command to use for a microcomputer containing a Quantum Model Q540 hard disk configured as unit 0 controlled by the iSBC 186/224A or the iSBC 214 board would be:

SUBMIT I TAPE : FORH_DISK( QMAo, 1, 5000 ) <CR>

A valid command to use for a microcomputer containing a Maxtor Model XT-1140 hard disk configured as unit 0 controlled by the iSBC 186/2244 or the iSBC 214 board would be:

SUBMIT :îAPE:FoRM-DISR( MMAo, 1, 17500 ) <CR>

A valid conrnrarrrl to usc lor a microcomputer contahing a Tosl ba Model MK56FB hard disk configured as unit 1 controlled by the iSBC 215G board would be:

SUBl4lT :TAPE: FORÌ.f,DI SK (Tl,lA1 , 4, 10625) <cR>

After the formatting of the hard disk is complete, the FORMAT command wiÌl issue a summary of the alternate tracks it assigned on the hard disk. Most hard disks contain bad tracks when they are delivered from the manùfacturer so this is a normal condition, and assigning alternates is the mcrhod iRMX II uses to compeosate for bad tracks. The message printed starts with the line:

The lollouinB tracks hawe been assigned an allernate:

{disk inforùrstion }

Next, the DISKVERIFY command is e.xecuted to check the formatting of the hard disk.

Following the DISKVERIFY command, the FORM-DISK.CSD SUBMIT file contains a series of the character 'y'. The 'y' is placed in the SUBMIT file to respond to any queries the DISKVERIFY command may issue. If the DISKVERIFY command does not make any queries, the crror messagc 'illegal command' is issued which has no effect on the installation process. You should ignore this error message.

The iRMX lI files will be added to your system from the tape automatically when the SUBMIT file invokes the Human Interface RESToRE command.

OPTION B: Formailing Only Track 0 of Your Hard Drive

This option formats only track zero of your system's hard disk and then places th€ second stage of the Bootslrap l,oader on this track. No fi.les on the disk will be affected by this option. You should choose this option ifyour disk was formatted using iRMX 286 Release 2.0 or iRMX E6 R€lease 7.0.

Notc that you can also boot load the iRMX 286 Release 2.0 or iRMX 86 Release 7.0 Operating System from the same hard disk using the new second stage.

In selecting this option, you obtain the capabilities ofthe Bootstrap Inader's DEBUG s,witch. Refer to the EÍeÍ&d |RMX II BootstraD Loa.d.er Refercnce Manual for detais on the DEBUG switch.

Reúeúber: You must insert the cartridge tape before invoking this following command.

To format only track 0 ofyour hard disk and install the Release 3.0 files, type the SUBMIT command below:

device name is the physical name ofyour microcomputer's hard disk. Refer to Table 3-2 for the appropriate physical device names for hard disks used in Intel microcomputers. Note that the device name is not a logical name so it does not have coìons surrounding it.

This SUBMIT file will ensure the system manager has full access to the directories and files affected by the installation process. It will also rename the following iRMX 286 R3.0 diectories and then will re-c.eate them for Release 2 installation:

Release 2.0 Name

This is done as a precautionary measure to avoid inadve.tantly modilying any ofyour existing files. A later section describes how to merg€ the contents of the renamed directories with the newly created directories.

Performing this option will cause the DISKVERIFY command to be invoked using the

"FIX" option. The "FIX" option automatically upgrades the file structure by including accuÉte checksums for each file.

As úe DISKVERIFY utility execut€s, it ìrill correct discrepaocies it finds on the hard disk. Refe. to the Eúended íRMX II Dísk Veification Utilitt Reference m rùalÍor information on the meaning of these messages. If your hard disk was previously fo.matted using the iRMX 86 Release 7 or iRMX 286 Release I Operating System, this SUBMIT file will compute checksum values for the file structure on the disk. When this occurs, the following message, indicating that co.rertive action has been taken, Ìvill be repeatedly printed to the screen.

Following the DISK\G,RIFY command, the FoRM-TRK0.CSD SUBMIT fiÌe mntains a series of the character 'y'. The 'y' is placed in the SUBMIT file to .espood to afly queries the DISKVERIFY command may issue. If the DISKVERIFY command does not make any queries, the error message 'ill€gal command' is issued which has no effect on the i-dstallation process. You should ignore this error message.

This option saves the old version and temporarly creates new versions of the system configuration files :CONFIG:TERMCAP, :CONFIG:TERMINA6, :CONFIG:UDF and all the :CONFIC:USER/ < user-name > user conliguration files.

Your old iRMX files now exist in the /RMX286_R2 directory. You may wish to generate Release 2 versìons of the Operating System. Refer to Retaining An Older Version of the Operating System for instructions on how to do this.

The iRMX II files will be added to your system from the tape automaticaÙy when the SUBMIT file invokes the Human Interface RESTORE command.
