I thought I'd be clever and buy a DVD for 5.2 from LinuxOnline.biz. Well, just got around to trying it with the above results. Does the error mean I have a 'bad' DVD disk image? Please advise. Thanks.

Boot from the DVD and at the boot prompt, type "linux mediacheck" (without the quote marks). That will check the DVD, to see if it checks out OK. That said, a few days ago, I installed from a DVD that did not pass "linux mediacheck" and that box is running OK. YMMV. HTH
Thanks Larry. Not even getting to a boot prompt. First time, it was saying: 'Press any key to try again'. - gives same results. I've been Googling the above. It seems that there are some incompatibilities that others have reported with Isolinux? I'm wondering if others here have seen the problem here? I know about the checksum error thing. I've done other installs from CD's without a problem. Thought a DVD would be a better install medium. Perhaps with my Intel D875PBZ motherboard, there is a conflict loading ISO images? Don't know. Haven't found any workarounds if that is indeed the case. I have the latest Intel bios. Is there one install medium provider that most prefer? To be sure to get good disks. I'd prefer getting a disk(s) from someone rather than trying to burn my own. Thoughts, advice appreciated. Thanks.

I suspect it is not a medium problem but rather an incompatibility (or bug) with isolinux and your DVD drive. So most likely the same would happen with any other provided media (or own-written media).
I would suggest comparing the MD5 or SHA1 from the DVD with the online provided checksum to make sure the image is intact. But the chances are really slim that the isolinux bootloader got corrupted, so I doubt it will make a difference...
Thanks Dag. I'm wondering if I'll have a similar problem with a multi CD ROM set instead of the one DVD? The system loaded RHEL WS 3, update 4 Taroon just fine from CD's. I'm leaning towards the same issue you mention. The large DVD ISO image is not recognizable by the system. At the time the system was put together, there were no DVD ISO images, just CD. The DVD ROM drive works just fine. Plays movies etc. The dual boot, Win 2000 Pro / Red Hat system would not mount the DVD however. Win XP, separate newer machine with a Samsung DVD reader mounts disk just fine and reads contents before freezing. It has a Plextor 712SA DVD RW unit. The older system has an HP DVD writer 300i. I don't recall who made the other DVD ROM. What do you think, could a CD ROM set solve the boot problem?

Hello William;
Are you thinking BIOS update for the motherboard or for the DVD drive, or both? The motherboard has Intel's latest and greatest. The DVD drive I'm not so sure of. It's been awhile since I looked at it's status vis-a-vis bios versions. I've not found bios updaters under Linux. Windows, yes; Linux no. I could remove the drive, put it into the XP box and check it's version that way? Don't you think it may be easier to try the CD set instead? They're about $7.95. The DVD was $4.95 with $5 shipping. RHEL 3 installed easily that way, back in the day. It took 9 CD's at the time. CentOS comes on 6. What do you think? I thought it would be easier to use a single DVD, not envisioning it might be a problem. Dumb me.

Both. On CD and DVD drives, I've always checked for updated BIOSs.

I use one of the free DOS versions on a floppy to do it. They say "Windows" because most of the great unwashed masses don't realize that Windows is still DOS based. The rest is marketing glitz and glimmer from MS with the real value provided by third party folks - drivers, etc.

Well, my 5.2 is on a box I built a couple years ago, EPOX 8KRAIPRO with a LITE-ON DVDRW SHM-165P6S that's about 1.5 years old (IIRC). I burned the DVD and installed from it w/o problem though. I would think newer equipment should have no problem if installation, drive and media are good.

Do you have another DVD (MS Windows or something else) that you can boot off of? I wonder if you can boot the Live CD for CentOS 5.2 and run from that.. That would show you whether or not this OS will run on your HW. Do you have any Diagnostics you can run on your DVD Reader/Burner, to see it working properly? If not, possibly you can get the Diagnostics from the manufacturer of the drive or if it was installed in your PC when you bought it, from the manufacturer of the PC.
