If that can be done by a simpel command, deciding what to put in your grub is a lot easier for http://www.opensuse.org/Installation_without_CD It works great when you know what to add in grub, but I understand that people might be baffled with what to put where and that not all IDE things count. houghi -- Quote correct (NL) http://www.briachons.org/art/quote/ Zitiere richtig (DE) http://www.afaik.de/usenet/faq/zitieren Quote correctly (EN) http://www.netmeister.org/news/learn2quote.html

Well, with me it is hd3,2.

No, that is not correct. That does not hold any information about what grub has. Where whould a program or script get the (hd3,2) info from that? I think I am not being clear. I am looking for a command or program or script that translates either /media/data or /dev/hdf3 to the correct root information. I am able to calculate it myself. I just want the computer to do it for me. A command that has /dev/hdf3 as input and hd3,2 as output (or whatever is correct) houghi -- Quote correct (NL) http://www.briachons.org/art/quote/ Zitiere richtig (DE) http://www.afaik.de/usenet/faq/zitieren Quote correctly (EN) http://www.netmeister.org/news/learn2quote.html

I have a bit more information. Say I have the Alpha 1 all in /media/data/opensuse/DVD_10.1_A1 That means that linux and initard are: /media/data/opensuse/DVD_10.1_A1/boot/loader/linux /media/data/opensuse/DVD_10.1_A1/boot/loader/initrd Now /media/data is /dev/hdf3, so I must enter the following in grub: title DVD_10.1_A1 root # Later kernel /opensuse/DVD_10.1_A1/boot/loader/linux initrd /opensuse/DVD_10.1_A1/boot/loader/initrd Now I still need to know what root is. I can do this by counting. I can also do this by lauching `grub` as root and enter: grub> find /opensuse/DVD_10.1_A1/boot/loader/linux This gives me : (hd3,2) Any way I could do this without entering grub? houghi -- Quote correct (NL) http://www.briachons.org/art/quote/ Zitiere richtig (DE) http://www.afaik.de/usenet/faq/zitieren Quote correctly (EN) http://www.netmeister.org/news/learn2quote.html

Now /media/data is /dev/hdf3, so I must enter the following in grub:

Not to my knowledge. BUT, you said that /media/data is /dev/hdf3 and grub gives you (hd3,2). This is incorrect as I understand. 'f' is the sixth letter which would translate to the digit 5, the sixth digit counting zero. I believe it should read (hd5,2). Also remember, the number of hard drives is not relevant for the device location. It *is* the device location on the bus that determines the device name, /dev/hdf3, sixth device, third primary partition on the device. -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org HOG # US1244711 Photo Album: http://wahoo.no-ip.org/gallery2

Uh-oh... I was under the impression grub counted like this: /dev grub-speak === ======= hda hd0 hdb (presumed optical) hdc hd1 hdd hd2 hde hd3 hdf hd4 and so on... Partitions (examples): ============= hda1 hd0,0 hdd4 hd2,3 hdf2 hd4,1 and so on... - Carl

No it isn't. For grub, what's interesting is the ordering the BIOS uses (changeable in the device map) I don't think it would be too much difficulty ripping out the device identification bits of grub to a stand-alone utility. But isn't "cat /boot/grub/device.map" sufficient?

The way grub-install does it is df `dirname filename| sed -n 's%.*\(/dev/[^ ]*\).*%\1%p' I'm looking at the BIOS stuff in grub now to see if I can make a stand-alone utility out of it

I think I am going in circles here. The above (if you put a backtick in front of |, making it filename`| ) tells me /dev/hdf3. That still does not show me hd3,2 Would be handy if all could be done with one command. :-) Strange that something that should be simple takes so much effort. houghi -- Quote correct (NL) http://www.briachons.org/art/quote/ Zitiere richtig (DE) http://www.afaik.de/usenet/faq/zitieren Quote correctly (EN) http://www.netmeister.org/news/learn2quote.html

OK. Here is the code I have made. Nit very good looking and too much grep and awk instead of sed. Also too many parameters. You run it as `bios /path/to/linux_kernel` At this moment it only outputs the grub information. I will edit it so that lilo will also work. I then will include it in makeSUSEdvd in such a way that if you run makeSUSEdvd it will tell you what to fill out in both grub and lilo config files. If anybody has an easier way, please let me know.

It is hd3,2. It boots with hd3,2 and even grub gives me 3,2 (See my other post.) This is how my IDE devices are: hda 10GB HD hd0 hdb 40GB HD hd1 hdc DVD --- Not a HD hdd DVD R/W --- Not a HD hde 160GB HD hd2 hdf 160GB HD hd3 hdg CD R/W --- Not a HD hdh empty The problem does no lie in how I can determine my root, because I know my hardware. The problem is explaining it on a page or putting it in a script, so others will know what theirs is and that in an easy way so they do not make the same mistakes as you did. ;-) houghi -- Quote correct (NL) http://www.briachons.org/art/quote/ Zitiere richtig (DE) http://www.afaik.de/usenet/faq/zitieren Quote correctly (EN) http://www.netmeister.org/news/learn2quote.html
