What I've read is that while many rebadges can use the actual manufacturer's firmware flashes, some can't.

I wouldn't upgrade the firmware unless you're absolutely positive that it'll work with your HP/Phillips. Actually all this is why the prevailing advice has always been to avoid rebadges in the first place... but that doesn't help you now ;) Also check that an upgrade actually fixes some bugs pertinent to your usage or adds capability, specially -dao (SAO).

Re: [newbie] Creating CD's from ISO images.
John, Ok, sounds like the same thing I have encountered. Write the CD to an ISO image on your HDD. If you don't want to do this via the CLI, perhaps the easiest way to do it is to use the Copy CD function within K3B. Once you click the tab to copy a cd, tick the box that says create ISO image only. Once it has completed writing the CD to an ISO, run the md5 sum on that ISO and you should be able to get a result. Remember, CD burning in Linux is not an exact science. From our local LUG archive (more details for you): = The implementation of the isofs in Linux is quite bad (e.g. the method of making inodes will prevent hardlinked files from ever being stored properly on an isofs). The kernel also has the habit (ever since the first version) of reading too much data from the device, i.e. it reads past end of file on the disk. Needless to say this can cause I/O errors (oh what a surprise). For this reason only cdrecord has a -pad option, which simply writes additional zeros past the end of the filesystem onto the disk. Of course, this also stuffs your md5 sums. Another bug in the kernel is that it can't properly detect end-of-file on CD media. These additional zeros will screw your md5. For the record, all these are 100% identical: cat /dev/cdrom | md5sum md5sum /dev/cdrom dd if=/dev/cdrom bs=2k | md5sum dd /dev/cdrom bs=2k | md5sum plus any more combinations everyone can think of. They either all work, or not at all. For current 2.4.18/2.4.19 kernels, they don't work reliably. Depending on how many blocks there are on the CD, reading will work, or fal with an I/O error (when the kernel tries to read past the end of the recorded bit stream on the media). Even if the read goes ok, unless you have happened to read precisely the correct number of bytes your md5 is screwed anyway. I have had kernels where cat /dev/cdrom resulted in a complete crash (kernel panick) right at the very end of reading. In my experience the only way to get reliable md5 sums with cds is to take matters into my own hands. Download the scriptutils package/tar from my web site and use writecd --blockread /dev/cdrom | md5sum or cook your own. The trick is dd bs=2k if=/dev/cdrom count=`isoinfo -i /dev/cdrom -d | awk ...` This will force reading of the correct number of blocks from the disk media (or any disk file). Note it will only work with an isofs on the CD, not with any other filesystem. Recently I got too fed up with this Linux isofs crap that I started to put ext2 onto the cds. Much easier and trouble free: create a 650MB or 700MB file filled with zeros (by reading from /dev/zero). Run mkfs -t ext2, don't forget -m0 as there really isn't any point in reserving blocks for the super user on a read-only filesystem. Loop-mount. Master your cd with cp, or rsync, or tar, or whatever, but no need to mess with mkisofs. Unmount. cdrecord file to cd, finished. Won't be readable by microsofties, but for my backups that's just as well. == Cheers Jason John Richard Smith wrote: Jason, ]# md5sum /dev/cdrom long wait md5sum: /dev/cdrom: Input/output error ]# this on unmounted drive.

Re: [newbie] Creating CD's from ISO images.
file would have a different md5sum from a burnt ISO file to disc, where the contents of that ISO file is written not the ISO file itself. My No - the ISO and the cd are (or at least should be) the same thing -- because an ISO is simply an image of a CD, bit for bit identical. It's kind of like an archive - for instance if I took an image of a tape written with 'tar' it would be the same thing - in this case, a tar file. reasoning being that an iso file may be compared to a locked suitcase of books, against a shelf of books all individually available ? I guess so, but think of it as an archive of files. The packaging (or to use your analogy of a suitcase) is transparent; the ISO is the collection of files, not just a set of files packaged into another file, because that implies packaging headers and so forth.

Burning at 4x is a good idea no matter what higher speed the media and burner are capable of, or claim.

Anne Iso's burned from the CL with... cdrecord -v -eject speed=4 dev=0,0,0 -dao name_of_the.iso ...will provide a CD that will still give a true and valid md5sum. IOW's you can easily check the integrity of the burned CD with 'md5sum /dev/scd0' and it will exactly match the one obtained with 'md5sum name_of_the.iso' . I've yet to see a GUI frontend for cdrecord or cdrdao, no matter the point'n click settings used, that doesn't produce altered images where the md5sum will still match reliably. Hence, checking actual integrity of the burned CD is impossible. YMMV -- Tom Brinkman Corpus Christi, Texas Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

I've never had to worry about md5sums until now--just finished d/l'ing 9.1 and I'm ready to burn! But my writer doesn't support -dao.

Our clocks DO go round counter-clockwise - but here, counter-clockwise is the way that y'all's clocks go. In the Southern Hemisphere, we have 10% more daylight per annum than does the inferior Northern Hemisphere, hence the breakdown in most of Western Culture because most of Western Culture, at least the inferior side of it, lives in the Northern Hemisphere. Due to the North Pole's wobble effect, those living in the Northern Hemisphere experience more blond moments than do those living in the Southern Hemisphere.
