sco open ser. ver.5 need help changing root pwd 1

[ghostrider7]

I purchased a computer to help me in my studies with sco openserver ver.5 this semester and i cannot unzip the boot img that i downloaded from ftp site at caldera. I need to unzip it in order to use rawrite for windows to make a boot floppy to change the root password that did not come with the computer. can you please help me with this?

I'm not sure what boot image you have downloaded, but i find it hard to believe that it would be in a zip format.

what size is the file you downloaded?
if it has a .Z extension then it will be "compress"ed
if it has a .gz externsion then it will be gnu zipped which is not compatable with pkzip.

sisz if download: 1.20 MB
file name: oss431a.boot.z XP Pro identifies it as an winzip file but winzip wont touch it. so I set up my redhat 9 box and i am going to try to uncompress it with it.the SCO openserver version 5 has POS by assal corp. on it I know the PWD for the pos terminal to start it but I want to get rid of POS and really learn SCO. I only paid 50.00 for the server and 5 clients from my boss when he upgraded. but i need any help you can offer.

As Stan says, this looks like a compressed file. If you're correct and the file has a .z extension, change the extension to .Z (ie a capital z) using mv filename.z filename.Z, as compress/uncompress doesn't like lower case extensions. Uncompressing the file should then work. HTH.

You can use zcat whith .z file, or uncompress.

the .z extension is created by 'pack' command. use the 'unpack oss431a.boot.z' to uncompress the file. From there try using the cpio to open it.

 

[stanhubble]

no the oss431 files are "compressed"

your windows machine probably changed the case of the .z

once you have the file on your redhat machine you can rename it and then uncompress it.
then you can dd it to a floppy.

dd if=./oss431a.boot of=/dev/fd0

I was able to transfer the file to my redhat box which then indicated a '.Z' final extention. I used the extract tool with redhat 9.0, worked great. Now it indicates an image of 1.4 MB. But being still new to the linux/unix world i am having a problem putting the file on floppy. redhat gives me an ERROR that the floppy is too small. How do i image it to the floppy? I can't use the SCO box do to lost passwords.I have used rawriten for windows before but now i cannot cut and paste it back to the shared folder on xp pro to use rawriten. I have both boxes on a network to share files and xp doesn't like linux. i even mounted the floppy, i tried formatting the floppy with fat and linux formats but too no avail. what am i doing wrong? is there a book that i can buy that will help me with SCO and Linux Redhat 8.0 and 9.0?
i need lots of help and i appreciate everyones help with this.

also the 'dd' in the terminal window gave me an error. said type 'dd --help' but that didn't help either.

 

[stanhubble]

The resulting file is an image of the boot floppy, not a set of files to be put on a floppy.

Did you cut and paste the dd command example that i suggested?

You should be able to use rawrite on the uncompressed image as well as dd.

I tried the dd command in the terminal window and it states that 'no such file found' I know on a windows platform you would give the exact location of the file i.e. directory/folder/file

the image is located in root/joseph/oss431a.boot

how do i tell the terminal where to look? can i use wildcards?
dd if=root/joseph/oss431a.boot of=/dev/fd0 will this work?

i don't want to do anything that will cause a fubar.
I really do appreciate your help. i just have not had time to play with linux due to school with this unix course comming up. Thanks

I was making a small mistake on my part when i was using the terminal window. Your directions worked perfectly. I greatly appreciate all your help in this matter with the boot image to floppy. Thanks.
