Hello,

I just downloaded all 4 iso images to my XP system. I burnt all the images to 4 separate CDs, and transferred to my Linux machine using dd. But looks like my MD5SUM check failing for all of the iso images. I guess this has something to do with my burning iso files to CD at Windows XP ?
Anyway, right now I just download one iso to my Linux machine directly, and MD5SUM passed. So, I am downloading rest 3 iso files. I have few questions:

1. I tried to use dd to burn CD-R from Linux, but it says "readonly" - and thats why I tried to download it to XP first. But looks like it is not working.
Can I not burn my CD-R using dd ? My Linux distribution is RedHat 7.2, and I issued command:

dd if=/root/FC3-i386-SRPMS-disc2.iso of=/dev/cdrom bs=144000

But other way it works. May be because of my CD-R ? But why I was able to burn from XP ?

2. Is there anyway I can install my Fedora core 3 from Hard Disk ? Because now I am trying to download all other iso files to my Linux machine. All the files will be stored in my /root/ directory.


Appreciate anybody's reply on this.

Thanks

Stop the presses! Unless you have more experience than looks like, you don't want to download SRPMS iso images. They should look like this ....
FC3-i386-disc1.iso
FC3-i386-disc2.iso
FC3-i386-disc3.iso
FC3-i386-disc4.iso

I use cdrecord to put the iso onto cdrom ....
cdrecord -v dev=0,0,0 -data FC3-i386-disc1.iso

Thanks, I believe cdrecord should work..I haven'e tried it yet, I will as soon as I am done with my downloads.

After I create all 4 cds, should I just put the first one - and try to boot my machine (using reboot) and I hope the installation will take place ?

Thanks, and appreciate your one more reply.

Hmmm, I'm pretty sure you can do a network install of FC3 if you have another PC on your home network (unless they've changed it, I installed RH8 or 9 w/ network install), and I know you can install it off of a second HD set up as a primary slave (hdb), but I'm not sure about HD. If you're having trouble burning ISOs, make sure your burner isn't burning the iso file (i.e. it's burning the image) and if that doesn't work try lowering the burn speed to around 16x. You shouldn't have any other problems from there.

well I tried using following command:

cdrecord -v dev=0,0,0 -data FC3-i386-SRPMS-disc1.iso

it says scsidev:0,0,0 scsibus: 0 target: 0 lun: 0
cdrecord: No such device. Cannot open /dev/pg0. Cannot open SCSI driver.


Also, I dont have any other PC to install - so network install is in no question. Iguess the choice I am taking is to burn CDs and then install. My previous question still remains, if I put the first disk, and I reboot the machine should take automatic installation.

Thank you for your help

The part about dev=0,0,0 may be different on your machine. Run the command:
cdrecord -scabus to find out what your dev is.

Did you see what I said about you downloading the wrong files?

Thanks..I see the same files as you listed..currently I am still downloading ..I have one more left..in the meantine I am trying to follow your cdrecord usage. Yeas, I checked cdrom -scanbus , and this returns No such files or directory, cannot open SCSI driver. For possible targets try 'cdrecord -scanbus'. Make sure you are root...

I checked ls -al /dev/pg* and it lists /dev/pg0, /dev/pg1, /dev/pg2, and /dev/pg3 (only four). Also I checked /etc/cdrecord.conf....this has CDR_DEVICE=yamaha, CDR_SPEED=4, CDR_FIFOSIZE=4m...and also in the commented line it shows yamaha = 1,5,0...and I tried again with the same command with dev=1,5,0...doesn\t work.


Anything else ? Let me know..I am sorry to kill your time..

Thanks

That should be cdrecord -scanbus
You can try that as root user.

Also run the command: dmesg | grep hd
and look to see what your cdrom device is. On my box that looks like this ....
hdc: ATAPI DVD-ROM drive, 512kB Cache, UDMA(33)
hdd: ATAPI 32X CD-ROM CD-R/RW drive, 4096kB Cache, UDMA(33)

Then on older systems like Redhat 7.2 you need a line in your lilo.conf or grub.conf which looks like this on the end of your kernel line....
hdc=ide-scsi or hdd=ide-scsi

No problem as I like to help.

I see a long list that includes (dmesg | grep hd)

hdc: ATAPI 40X CD-ROM drive, 128kB cashe, DMA

also I dont see /etc/lilo.conf , but I have /etc/lilo.conf.anaconda

it has ...

Quote
prompt
timeout = 50
default = linux
boot=/dev/hda
map = /boot/map
install=/boot/boot.b
message=/boot/message
liner

image =/bot/vmlinuz-2.4.7-10
label=linux
intrd=/bot/initrd-2.4.7-10.img
read-only
root =/dev/hda2

Unqute

I howevere, found /etc/grub.conf where I have

Quote

timeout=0
splashimage=(hd0,0)/grub/splash.xpm.gz
title...
root(hd0,0)
kernel /vmlinuz-2.4.7-10 ro root=/dev/hda2
initrd /initrd-2.4.7-10.img
Unquote




Should I add hdc=ide-scsi at the enf of this lilo.conf.anaconda file or /etc/grub.conf?

And then ?

Try it in the /etc/grub.conf
kernel /vmlinuz-2.4.7-10 ro root=/dev/hda2 hdc=ide-scsi

You need to reboot for that to take effect.

Now I see following when I issue command "cdrecord -scanbus'

Cdrecord 1.10............
Linux sg driver version:3.1.19
Using libscg version 'schily-0.5-
scsibus0:
cdrecord " warning controller returnes wrong size for CD capabilities page

0,1,0 1) *
0,2,0 2) *
...
...
0,7,0 7) *

......................................

So, I assumed my dev=0,0,0 , and issued the same command
cdrecod -v dev=0,0,0........

Shows all the messege...I thought it copied...but when I tried to mount using
mount /dev/cdrom /mnt/cdrom - it shows
mount: block device /dev/cdrom is write protected, mounting readonly
mount: no medium found


Any idea ?

Sometimes you need to eject a freshly burned cd and put it back in to mount it. Also, if you can mount as root user, the /etc/fstab might not have those kind of rights for users.

Sorry to tell you that there was no image burnt at all...I am not sure if dev=0,0,0 is right for cdrecord as argument.

Again, please look at my previous posting where I listed my output from 'cdrecord -scanbus', and from there I assumed my argument should be dev=0,0,0 ...it may not be right..because now I carefully checked the error (I am listing error, and warnings both below) I found when I issue following command:

cdrecord -v dev=0,0,0 -data FC3...

cderecord:warning:controller returns wrong size for CD capabilities pages

Response Format :1
Vendor_Info : 'SAMSUNG'

cdrecord: Sorry, no CD/DVD-Recorder or unsupported CD/DVD Recorder found on this target



Clearly this didn't burn the CD. The reason I used dev=0,0,0 is that the vendor is SAMSUNG, and my 'cdrecord -scanbus' shows SAMSUNG is 0,0,0 ......


Can you help me figure out the problem please ?

Thanks for all your time giving me solving the issue....

Rafiqul

For your present operating system, dev=0,0,0 is correct.

cdrecord: Sorry, no CD/DVD-Recorder or unsupported CD/DVD Recorder found on this target

It could be that the version of cdrecord you have doesn't work with that cdrecorder.

If you have a cd burning program on XP, there is no reason you can't do it from there. You burn the image, don't just copy it over to the cdrom.

Thanks for your reply...
I will try to burn the CD from XP...And will give it a try.
I thank for all your time...and have a good night.
I will probably give it a try tomorrow...

Thanks
