Mandrake did more then hiccup, got to lido and errored "no init" since it was still loking for hdc. I even tried leaving it on hdc and removing the hdd(cdrom). Jumper set to single. Tried puting the second drive as slave (which should make it hdd). This system has only been running with the drives on the 2nd ide channel. The win drive has not been plugged in ide channel since mandrake has been running. Since the lido, and fstab both point to hdc. I can't get it to boot if I move the drive. Which files and pointers must be changed to get the drive to boot to at least a min running mandrake system? > > 2) add a new drive as hdb (then put the /var part on it) > > set hda as master on its jumpers, then plug your new drive into the same > data cable with it's jumpers set to slave > > > 3) make the CD writer hdc > > Set it up as a stand alone on the jumpers, ( ah.. whats the correct term > not master, not slave but <you-know> ). > > I hope you know what a jumper is and where to find it? > > > 4)kiss ms goodbye, opps did most of that many years ago, No inportant info > > stored or used on a ms machine, only games. > > > -- > In the future, you're going to get computers as prizes in breakfast > cereals. > You'll throw them out because your house will be littered with them. > >
