Isolinux Image Checksum Error
Image checksum error???Posted: Tue Mar 13, 2007 11:56 am Joined: Wed Dec 27, 2006 11:51 amPosts: etcdisolinux image checksum error sorry 14Location: GREECE Hello people. I tried to make my own mix of bootcds (as I always do and worked fine), by extracting the image ultraiso contents (luckily I have no folder conflicts), extracting the boot code and using easyboot to make a new image, and UBCD4 now gives me something like this: "isolinux: image checksum error, sorry..." Is there a way to trick the system to

boot? (somehow ignore different checksum or something) Thanks in advance. Also, how come and UBCD4 is so much smaller than UBCD3.4? Was the overhead so different? _________________--- NLS Top Constance Post subject: Posted: Tue Mar 13, 2007 7:10 pm Joined: Fri Sep 23, 2005 1:21 amPosts: 338Location: France If I remember well, Insert has been removed starting from version 4.

Is that of initial bootup or one of the folders? Top nls Post subject: Posted: Mon Mar 19, 2007 11:55 pm Joined: Wed Dec 27, 2006 11:51 amPosts: 14Location: GREECE What you mean? I found the total size of the image much smaller. Probably because of INSERT. Or you mean about the checksum error? I have a triple boot CD, where all three "original" CD fold
while booting Isolinux Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hi, > makehybrid \ > -o isos/muaaa.iso temp/ \ > -eltorito-boot temp/isolinux/isolinux.bin \ > -no-emul-boot \ > -iso -joliet -boot-load-size 4 \ > -default-volume-name "Custom Installer" \ > -eltorito-platform temp/isolinux/boot.cat > ... > [at boot time:] > Image checksum error, sorry http://www.ultimatebootcd.com/forums/viewtopic.php?t=847 I guess it is the Boot Information Table feature that's missing with your ISO production run. The boot image isolinux.bin expects to get patched by some parameters, including a checksum. See man mkisofs http://cdrecord.berlios.de/private/man/cdrecord/mkisofs.8.html paragraph "EL TORITO BOOT INFORMATION TABLE" Do i get it right that http://www.syslinux.org/archives/2013-November/021111.html "makehybrid" is a shortcut for hdiutil makehybrid as of https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/hdiutil.1.html There seems to be no option for above feature. Programs which can produce compliant ISO images are: program="mkisofs" program="genisoimage" program="xorriso -as mkisofs" Use one of them instead of your ISO production command: cd temp $program \ -o ../isos/muaaa.iso \ -b isolinux/isolinux.bin \ -c isolinux/boot.cat \ -no-emul-boot -boot-load-size 4 -boot-info-table \ -J \ -V "Custom Installer" \ . I read in man hdiutil that -eltorito-platform gets a parameter like 0. How come yours gets the name of the boot catalog ?

I am impressed with the features. But unfortunately I am not able to install because my downloaded iso image shows checksum error . I tried 3 times (from different mirrors) and in all cases my burning was successfull. But when I tried to boot, I got the message 'iso linux 2.04 (Debian 2003-06-06) isolinux : image checksum error, sorry boot failed' Please help. 02-02-2008,12:08 PM #2 amac Untangle Junkie Join Date Aug 2007 Posts 822 I think I remember people having issues with burning at faster speeds... what settings are you burning at. And what hardware are you trying to install on? 02-02-2008,07:04 PM #3 vinodsilicon Untanglit Join Date Feb 2008 Posts 22 I burned at 16X once and tried at 10X also. I use Intel Dual Core 3.0 GHz with 512 MB RAM and 40 GB HDD. I think hardware is not the issue because even I am not able to boot from the CD. Is there any way to check the checksum of the downloaded image ? Thanks.. 02-02-2008,08:10 PM #4 vinodsilicon Untanglit Join Date Feb 2008 Posts 22 Issue has been solved. I burned at 8X and it booted . My MD5 checksum was 0296ab40a520ac1a3f532a5e3105f690.
