khvn Posted July 22, 2008 Posted July 22, 2008 After creating a bootable Ultimate Boot CD (UBCD) ISO using IMGBURN's build option and burning it to a CD, I attempted to boot with the CD which failed with this error message: ISO Linux 3.35 2007-01-28 isolinux: Image checksum error, sorry... LUK was aware of this issue and has mentioned about a patch for this in this thread: http://forum.imgburn.com/lofiversion/index.php/t6793.html It appears that the fix has not been incorporated in IMGBURN 2.4.1.0 because this is the version I used and ran into the problem described above. Does anyone has any update/work-around for this? Thanks!
LIGHTNING UK! Posted July 22, 2008 Posted July 22, 2008 2.4.2.0 ? The file must be exactly as I describe in the changelog though.
khvn Posted July 22, 2008 Author Posted July 22, 2008 2.4.2.0 ? The file must be exactly as I describe in the changelog though. Whoa, 2.4.2.0!!! Alright, new toy from LUK (The Disk Walker?)!!! When did 2.4.2.0 come out? I didn't know! Thought I have the latest! Will try it out tonight and report back here. Could I have a link to the changelog? Thanks!
khvn Posted July 23, 2008 Author Posted July 23, 2008 Bad news: The boot problem persisted in 2.4.2.0. The boot failed with the same message: ISO Linux 3.35 2007-01-28 isolinux: Image checksum error, sorry... Following are the settings I used for the "build" option (options not shown used default values) Options: -------- File system = ISO9660 + Joliet Preserve Full Pathnames Recuse Subdirectories Include hidden files Include system files Labels: ------- ISO9660 = MYUBCD Jolie = myUBCD Advanced: ------------ Restrictions: -------------- ISO9660: ----------- Folder/filename length = Level 1 Char set = standard Allow more than 8 dir levels Allow more than 255 chars in path Allow files w/o extensions Don't add ";1" version number to files Bootable Disc: ----------------- Make image bootable Emulation type = None (custom) Boot image = correct path to file (extracted from original UBCD CD) load segment = 07C0 Sector to load = 1 I hope ImgBurn 's ok and it's me who missing something? Also, is there any tool that can test-boot bootable ISO images without having to burn real CDs?
LIGHTNING UK! Posted July 23, 2008 Posted July 23, 2008 The 'boot image' should point to the isolinux\isolinux.bin file in your file structure. The sectors to load should be 4. I'm not so sure you want 'Preserve Full Pathnames' enabled - that could prevent things from working correctly. If the folder & file 'isolinux\isolinux.bin' doesn't exist in the root of the image then no patching will take place. For testing without burning you can just build an ISO and try to boot it in vmware / some other virtual machine program (having mounted the image as a drive).

Summary: I changed the settings as you suggested above and the result was unchanged. The "isolinux: Image checksum error" was still there. What I'm trying to do: UBCD <- This Ultimate Boot CD boots ok | | ImgBurn: rips an ISO from this CD | V UBCD.ISO | | WinImage: Extracts folders & files from this ISO image | V File Structure | | ImgBurn: builds an ISO from this file structure | V UBCD.ISO | | ImgBurn: burns this ISO to CD | V UBCD <- This CD failed to boot Settings: A snapshot of the file structure used for the build: iso_content.bmp Following are the settings I used for the "build" option this time (options not shown used default values) Options: -------- File system = ISO9660 + Joliet Recuse Subdirectories Include hidden files Include system files Labels: ------- ISO9660 = MYUBCD Joliet = myUBCD Advanced: ------------ Restrictions: -------------- ISO9660: ----------- Folder/filename length = Level 1 - 11 chars, 8.3 format Char set = standard Allow more than 8 dir levels Allow more than 255 chars in path Allow files w/o extensions Don't add ";1" version number to files Joliet: ------- Folder/filename length = Level 1 - 64 chars Allow files w/o extensions Bootable Disc: ----------------- Make image bootable Emulation type = None (custom) Boot image = points to "~\ISOLINUX\ISOLINUX.BIN" load segment = 07C0 Sector to load = 4 Result: When booting with the freshly built UBCD ISO image with the Daemon tool I got this error: "Windows cannot find 'website\index.html'. Make sure you type the name correctly and try again..." and the boot died. When I went ahead and burn the UBCD ISO image (using ImgBurn) to a real CD to test anyway, the "isolinux: Image checksum error, sorry..." was still popping up and the boot died.

LIGHTNING UK! Posted July 23, 2008 Posted July 23, 2008 Could you please examine the ISO in IsoBuster and look at the LBA of the bootimage and compare it to the actual isolinux\isolinux.bin file on the disc. They *should* both be the same!

They *should* both be the same! Hi LUK, I don't have ISObuster so I worked around it as follows (please tell me if it's good enough): Note: extract = extract via WinImage (1) I established a pre-built "isolinux.bin" which is the version I extracted from the UBCD ISO image that has been ripped from the original working Ultimate Boot CD. The pre-built "isolinux.bin" should be error free since it came straight from the ISO image of a working CD. (2) Next is the built "isolinux.bin" which is the version I extracted " from the "built" UBCD ISO image that failed to boot. (3) I then compare the built "isolinux.bin" with the pre-built "isolinux.bin" by inspecting the file property of the 2 versions and saw that their size & size-on-disk are exactly the same. since their size are exactly the same, I thought chances are they are the same. Is this good enought or you would like a bit-by-bit comparo between the 2 files via some kind of diff tool? One interesting fact: I check and saw that the "built" ISO is actually a bit smaller than the "pre-built" ISO. So looks like something has been missing from the "built" ISO during the build.
LIGHTNING UK! Posted July 24, 2008 Posted July 24, 2008 Can't you just download IsoBuster? It's free. Patching doesn't change the size of the file so you can go by size alone.
khvn Posted July 24, 2008 Author Posted July 24, 2008 Can't you just download IsoBuster? It's free. Patching doesn't change the size of the file so you can go by size alone. LUK, ISObuster shows that both the pre-built and the ImgBurn built isolinux.bin files have the same size (10,932 bytes), but their LBA's differ. pre-built LBA = 252 ImgBurn built LBA = 57311 Would this be relatively a quick fix setting the ImgBurn built LBA to the correct address?
LIGHTNING UK! Posted July 24, 2008 Posted July 24, 2008 Sorry, I probably wasn't clear. Within IsoBuster, click on the 'Bootable Disc' entry on the left and see what the LBA is for the BootImage in the right pane. Then compare that to the LBA of the ISOLINUX\ISOLINUX.BIN file in that same image via the 'ISO' or '>>>' (Joliet) entry on the left. Different LBA's between images is perfectly fine and to be expected - so don't compare different images! If ImgBurn has patched the file at all, both the bootimage and the isolinux.bin with have the same LBA. If they don't, it hasn't Basically, when it patches the file, the one you specify for the bootimage is ignored because it really just points to a proper file in the file system.

Sorry for my ignorance! I checked again and the LBA's for all three entries, 'Bootable Disc', 'ISO' and '>>>', are exactly the same (72842). I understand your explanation about different LBA's are ok from image to image, but it may be worthwhile to point out here that the ISO built by WinImage, which has no boot issue, set the same LBA values (252) as in the original pre-built ISO.
LIGHTNING UK! Posted July 24, 2008 Posted July 24, 2008 Ok, next I need you to right click on the isolinux.bin file within the ImgBurn built ISO file (We're still using IsoBuster for this) and select 'Sector View'. Post up a screenshot of that window.
LIGHTNING UK! Posted July 25, 2008 Posted July 25, 2008 Damn, I think I got my CRC calculation wrong. I was doing it byte by byte but I think I need to do it dword (4 bytes) by dword. I might get you to test the change if that's ok?

khvn Posted July 25, 2008 Author Posted July 25, 2008 Damn, I think I got my CRC calculation wrong. I was doing it byte by byte but I think I need to do it dword (4 bytes) by dword. I might get you to test the change if that's ok? Sure, LUK! Just let me know what I need to do.

I might get you to test the change if that's ok? Sure, LUK! Just let me know what I need to do. Anything to test, LUK? Just want ImgBurn to work so I don't have to mess with ye olde venerable "mkisofs" again...
LIGHTNING UK! Posted August 1, 2008 Posted August 1, 2008 Sorry, I'm away at the moment (until the 19th) and can't do anything on ImgBurn.
roothack Posted August 2, 2008 Posted August 2, 2008 At least I know I'm not going crazy. I was trying to make a remaster a Red Hat Enterprise Linux install with a custom kickstart script and could not figure out what I was doing wrong. Work around in the meantime (if you have access to a *nix box) is to use mkisofs command. mkisofs -r -T -J -V "Volume title" -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /path/to/output.iso /path/to/sourcefiles/ Thanks LUK for great software, been a long time user.
