At start up of my PC, using the first Fedora Core II Cd, I got the following error :

ISOLINUX 2.08 2003-12-12 isolinux: Disk Error 01, AX=4271, 9F


Someone can help me ?

The CD is busted. Get a new CD or try burn it again.

I saw this error when I tried to install FC2 on an HP laptop. The CD was
not busted; it passed the media check and in fact I used the same disk to
install to a desktop machine.

The problem in my case at least appears to have been a brain-dead BIOS
that would only allow bootable CDs that used floppy emulation. The
solution I used was to create a new bootable CD using DR-DOS and LOADLIN
to start the FC2 installer.

Thank you John,

I think that you could have reason.
In fact, the CD is working on another computer and I had the same
problem with other Linux distributions even thougth some distributions
works.

I'd like to follow your procedure, but I haven't DR-DOS and LOADLIN.
Can you suggest me where to find out the tools ?

Thanks in advance,
Valerio

I used DR-DOS but you can use any DOS boot diskette. You can get a
variety from http://www.bootdisk.com. Basically, download the boot
diskette image, make sure it supports CDROM devices (you can mount the
image through the loopback device: eg, "mount -t vfat -o loop disk.img
/mnt/tmp" to mount it on /mnt/tmp, then you can check AUTOEXEC.BAT and
CONFIG.SYS for the needed support:

[AUTOEXEC.BAT]
@ECHO OFF
rem LH MSCDEX.EXE /Demcd001 /L
LH NWCDEX.EXE /Demcd001 /L

[CONFIG.SYS]
rem device=himem.sys
device=emm386.exe
device=oakcdrom.sys /Demcd001
device=btdosm.sys
rem device=flashpt.sys
device=btcdrom.sys /Demcd001
files=60
buffers=20
dos=high,umb
stacks=9,256
lastdrive=z

If yiour computer has a floppy drive, you can simply write the image to a
floppy ("dd if=disk.img of=/dev/fd0") and boot from it to test.

If you don't have a floppy drive, you'll need to make a bootable "el
Torrito" CD disk using the floppy image. Copy the first FC2 CD contents
to a directory somewhere. Create a new "boot" directory at the top level
of that directory. Copy the disk.img file into that directory. Then
you'll need to track down LOADLIN.EXE; I think RedHat has it on their ftp
site, but I just copied the whole DOSUTILS directory from the FC1 install
bootdisk into the FC2 directory. Edit the DOSUTILS\AUTOBOOT.BAT file so
it reads:

loadlin isolinux\vmlinuz initrd=isolinux\initrd.img ramdisk_size=9216 %1
%2 %3 %4 %5 %6 %7 %8 %9

(all on a single line). You then make the iso using mkisof:

mkisofs -r -b boot/disk.img -c boot/boot.catalog -o bootcd.iso .

Finally, burn the iso to a CD using cdrecord:

cdrecord -v -fs=16m -eject bootcd.iso

Hi John,

you have been really exaustive.
I'll try to follow your suggestions, then I'll let you know the result
thanks a lot

Just had this same error on an AX6BC motherboard, several years old.
Updating the BIOS fixed it. The old BIOS wouldn't recognize a
bootable CD.
