Cant boot off cdrom now.


I have mandrake 10 and added a cdrw to my computer. I made the new drive the master and the old the slave of course making the correct jumper settings. I also went into BIOS and made sure it was correct. After boot it asked if I wanted to configure the new hardware and I said yes I have to reload the OS on the computer because I have messed it up really bad. I have a lot of failures on boot and at this point it would be easier for me to start over. I am such a noob that I dont know another way. The problem I am having is that neither cd is recognized. I think the computer believes that the floppy drive is the master cdrom because on boot when the screen says boot off cdrom the green light on the floppy lights up. I dont know anything about linux and therefore I dont have a clue even how to come up with the info you need to help me. Please help. I thought that the initial boot was coordinated from bios so I dont understand why it wont boot from cdrom. Maybe the best thing here is to erase the hard drive from the command line. I dont know how to do that either

robby737; 1st thing 1st. ? bios tricky, correctly done operation goes smooth. assume u did it correct? this order 1.cd 2.hd1, 3. fd., 4. rest of partitions, along with cdrw. if so OS will then recoqnize them. check that out.

I dont think you understand. I dont even know what question to ask in the man pages. I was hoping for more help than that. I dont understan most of what the man pages say and just learned how to access them. This IS the newbie section. Please let someone else try to help. I dont think you understand what level of help I need

Hi there,

so you have a CD and a CD/RW on your system. You also verifyed in BIOS which drive is the master and which slave. Fine.

Did you also verify the Boot Order (Sequence) setting in BIOS ?
In every BIOS I have seen so far, there is an option for setting the
boot order (sequence), means in which order the devices are checked for a bootable media.

Verify that your CD ROM drive is there. The best would be if your old
and new CD ROM drive is in the boot list.

I don't know, if I can agree with the statement, that you encounter an OS Problem. An OS Problem would it be if there is something wrong during the boot process, but you
say that the boot does not even start. So how can it be an OS problem, when the OS is not loaded at all ?

There is also two more options: The CD you are trying to boot from (the media not the
drive) is *not* OK (corrupted media) *OR* you new CD-RW Drive can not
read the CD media. In this case try to boot from the CD using your old
CD-ROM Drive (of course it has to appear in the boot sequence list
in ROM).


Erasing drive: mkfs will create a new filesystem (it's similar to windows' format command)

About the drive mapping:

/dev/hda is the the master on the first IDE controller (or primary IDE channel)
/dev/hdb is the slave on the first IDE controller (or primary IDE channel)

/dev/hdc is the master on the second IDE controller (or secondary IDE channel)
/dev/hdd is the slave on the second IDE controller (or secondary IDE channel)

What drives are attached can be determined by:
ls /proc/ide

Example:
ls /proc/ide
produces on my system following output:
drivers hda@ hdb@ hdc@ hdd@ ide0/ ide1/ piix

Now you can query the type of the device. This is done by /sbin/hdparm -i.

/sbin/hdparm -i /dev/hdX
where X stand for the drive (a,b,c,d). Do not forget the /dev/ in front of the drive.

Example:
/sbin/hdparm -i /dev/hdc

produces on my system following output

/dev/hdc:

Model=_NEC DVD_RW ND-1300A, FwRev=1.08, SerialNo=
Config={ Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=unknown, BuffSize=0kB, MaxMultSect=0
(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
IORDY=yes, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 *udma2
AdvancedPM=no
