I don't know what you mean. Did you try to go to this web site? Was it
there?
Do you use any special options to cdrecord?
How could the drive's firmware be to blame if I burn on this same drive and
media with winXP/Roxio?
I use this same media and drive and using winXP/Roxio burn freeBSD 4.11 ISOs
and boot off them.
I'm doing this all on a 2.4GHz pentium, so I can't imagine it's a buffer
underrun, if winXP doesn't underrun the buffer.
When you burn at 40x, is that CD-R media?
I'm using Memorex CD-RW 4x-12x. I also have one piece of Memorex 1x-4x CD-RW
media, which DOES work. I tried to burn the 4x-12x media at 4x speed (which
is the speed used to successfully burn the 1x-4x media) but it still failed.
I don't believe it's a buffer underrun due to this. I think there's
something about the 4x-12x media that cdrecord is unaware of.
If someone has burned a Memorex High Speed (4x-12x) in a drive marked as high
speed (this is an actual official designation, and it's not the same as ultra
speed drives), I'd like to hear about it.
