I'm sorry I was not able to explain the situation. I believe it's a matter of "newbie-ness" and poor technical english. I apologise for that.
another problem probably arises around the word "disk mapping", that as far as I understand, has a twofold meaning:
one concerning the name given by BIOS or GRUB to the devices, the second is the "cheating" procedure from within GRUB, a sort of "virtual disk swapping",
Well', I try to put it in other words:
When I turn the coputer on, and I have a bootable CD in, I get the message "press any key to boot from CD".
So, I understand that the CD drive is on the BIOS list of boot devices.
As a matter of facts, before understanding grub's functionalities, I tried to install XP from the CD just making it boot the computer as asked by BIOS.
It all ended up in windows asking me to format the first disk (where SUSE LINUX) is installed, because it does not find a known partition to write the MBR on.
What I had to do, was to use GRUB as I've described earlier.
This has to be made before booting, I understand, so that when win installation goes on, it finds a good parition already prepared in the secnd HD, now virtually mapped as first.
That's what i mean when I speak about "a grub-managed" boot.
Well, I could install XP only via floppy start disks, downloaded from microsoft. But, of course, the whole thing was lengthy and boring (6 floppys).
Now that I want to install XP-64bit edition, which most likely has not floppy start disks available (I still have to check microsoft site), I need to manage a boot from CD by GRUB.
Hope I was more clear, this time.
