COULDnot install sco unix 5.0.0 using IDE CDDrive

[Guest_imported]

I try to install SCO Unix open server 5.0.2 on an intel based pc.But after giving CDDRIVE configuration an error came i.e.

" /tmp/cdrom cannot access.
check your bios setup
safe to turn off computer
or
press any key to reboot"


my pc's configuration is

Intel Celeron 566 MHz
Intel 810 chipset motherboard
64 MB SDRAM
10 GB Seagate IDE HDD
52X LG CDROM Drive (IDE)
14" Colour Mnitor
104 keys keyboard,
logitech 3 button mouse"

I connect my CDDRive as Primery slave
and give the values as per manual(SCO's)
what i will do?

Try connecting the CD on the secondary master - don't forget to change the jumper on the CD drive. Although SCO appears to allow any position for the CD I have found that Openserver only sees it as the secondary master.

Hi i found the following article at the sco web site and i hope this works for you.

How do I install OpenServer 5.0.2 with an EIDE (ATAPI compliant) CD-ROM reader?

Problem
I am installing SCO OpenServer 5.0.2 from CD-ROM media with an EIDE (ATAPI compliant) CD-ROM drive.

Note
This article contains information for installing SCO OpenServer 5.0.2 products from the disks and media included only with the 5.0.2 installation package. The corresponding procedure for SCO OpenServer Release 5.0.4 has been improved and is noted at pertinent stages of the procedure discussed below.

Solution
The "wd" driver is included on the SCO OpenServer 5.0.2 Boot diskette, one of two floppy disks included with OpenServer 5.0.2 installation media package. It provides support for most EIDE CD-ROM drives. In order to use an ATAPI CD-ROM, certain IDE restrictions apply, such as a maximum of 2 IDE controllers on a system, a maximum of 2 IDE devices for a single IDE controller, "MASTER/SLAVE" IDE device considerations, and "PRIMARY/SECONDARY" IDE controller selections.
NOTE: Before proceeding, check documentation provided by the EIDE CD-ROM hardware manufacturer for installation procedures, especially "MASTER/SLAVE" jumper settings and "PRIMARY/SECONDARY" controller settings.

Use the following steps to install OpenServer 5.0.2 with an ATAPI CD-ROM:

1. Insert the installation boot disk provided with your SCO OpenServer 5.0.2 software in the floppy disk drive and boot the system with it.

2. Enter &quot;restart&quot; or press <Enter> at the &quot;Boot:&quot; prompt.

NOTE: If the system has a primary SCSI hard disk that will be used as the boot drive, the bootstring must be altered to define that primary SCSI hard disk for the installation UNIX kernel. As an example, if the primary hard disk drive has a SCSI ID of 0, a LUN of 0 and is attached to the primary bus controlled by an Adaptec 2940 host adapter (alad), use the following bootstring:


Boot: defbootstr Sdsk=alad(0,0,0,0)

where, in this example, the first &quot;0&quot; represents the first alad controller, the second &quot;0&quot; represents the first bus on that controller, the third &quot;0&quot; represents the target ID of the drive, and the fourth &quot;0&quot; represents the LUN of the drive .
NOTE: Starting in SCO OpenServer Release 5.0.4, the above bootstring extension is not necessary. The operating system should correctly match the ATAPI cdrom and SCSI hard disk to their respective controllers.

The following is a list of host adapters and matching driver names that are included and supported with the OpenServer 5.0.2 installation package:


Host adapter Driver name
----------------------------------------------------------
Adaptec 152x spad
Adaptec 154x,emulation, 164x ad
Adaptec 174x eiad
Adaptec 274x, 284x (7770 chip) arad
Adaptec 294x (7880 chip) alad
Future Domain 1650, 1670, 600, 700 (1800 chip) fdha
Future Domain 7000 wdha
Future Domain 7000ex wdex
Future Domain 845, 850, 860 (950 chip) tmcha
Olivetti ESC-1, ESC-2, and EFP efp
Storage Plus SCSI-AT (SUMO) sumo

3. When the &quot;Identifying the installation media device&quot; screen is displayed, choose &quot;SCSI CD-ROM&quot; as the media device type.
NOTE: starting in SCO OpenServer Release 5.0.4, &quot;CD-ROM&quot; will be the default media device, and &quot;wd&quot; should be listed as default if the ATAPI cdrom drive has been configured in the system. Of course, &quot;wd&quot; can always be selected from this screen if it is not the default choice. In this manner, the notion of &quot;ATAPI cdrom&quot; is made separate from &quot;SCSI cdrom&quot;, the the corresponding &quot;master/slave&quot; and &quot;primary/secondary&quot; parameters are chosen literally instead of converting them to SCSI-like parameters as in OpenServer 5.0.2.

4. Select &quot;wd&quot; as the SCSI host adapter type.

5. If &quot;wd&quot; is not shown as a SCSI host adapter type, quit installation and start again with the following bootstring:


Boot: restart Srom=wd(N,N,N,N)

where, in this example, the first &quot;N&quot; represents the primary or secondary IDE controller (0 for primary, 1 for secondary), the second &quot;N&quot; represents whether the IDE device is jumpered as master or slave (0 or 1), the third &quot;N&quot; represents the LUN of the drive (always 0 with the wd driver) and the fourth &quot;N&quot; represents the BUS id on the IDE controller (always 0 with the wd driver). It may also be necessary to include &quot;Sdsk&quot; information from step 2 in this new bootstring.
NOTE: If &quot;wd&quot; is not shown as a SCSI host adapter type, the &quot;wd&quot; driver was not able to detect the EIDE (ATAPI compliant) CD-ROM drive. Ensure that the settings for the CD-ROM, other IDE devices and CMOS settings for IDE devices, on that system are correct. On some systems it may be necessary to set that EIDE CD-ROM as a device on the &quot;Primary&quot; IDE bus as appropriate, that is, if the primary IDE bus only contains the EIDE CD-ROM then it should be jumpered as &quot;Master&quot;. If the EIDE CD-ROM is the second device with a boot drive as &quot;Master&quot; then the CD-ROM should be jumpered as &quot;Slave&quot;.

6. If the CD-ROM drive is attached to the Primary IDE controller in system with one or two IDE controllers, select &quot;0&quot; for the host adapter number.

If the CD-ROM drive is attached to the Secondary IDE controller in a system with two IDE controllers, select &quot;1&quot; for host adapter number.

7. If the CD-ROM drive is configured as a Master device, select &quot;0&quot; for its SCSI ID.

If the CD-ROM drive is configured as a Slave device, select &quot;1&quot; for its SCSI ID.

8. Select &quot;0&quot; for the SCSI LUN of the CD-ROM drive.

9. Select &quot;0&quot; for the SCSI bus number.

NOTE: starting in SCO OpenServer Release 5.0.4, steps 5-9 are replaced by simply choosing &quot;Master&quot; or &quot;Slave&quot;, and then &quot;Primary&quot; or &quot;Secondary&quot; to specify the position of the cdrom on the IDE bus.

See the SCO OpenServer Handbook to continue the installation.
