apologies if i missed something, but how does a USB 2.0 patch fix the HDD ATA speed that the OP complained of (unless ofcourse if it's in an external USB 2.0 enclosure - which the OP doesn't imply or state)

I was referring to:

... hdparm -t /dev/sda shows that my USB memory key is 1 MB/second, but it runs at 8 MB/second under Knoppix 3.6 or Fedora...

and the following reply:

I had the same problem. The solution was to load the usb 2.0 driver, ehci-hcd. Once I did that, I got the 2.0 speeds. FMI, see: http://www.linux-usb.org/usb2.html

I have never pretend solving all Linux problems.
I agree with you that the USB2 fix should only help with USB devices,
including USB2 HDD enclosures and USB2 dongles, which was my problem
and according to other posts, was also the problem of other Knoppix users.
On a side note, I believe that this way to patch the official CD/DVD iso
could be very usefull for other bug fixes and is quite interesting
since it will prevent the need for a Knoppix remaster.

I'm certain it did there was no offense at all intended (and I'm sure none taken), and I personally find much of the work you've done invaluable, and the info you've posted here at knoppix.net forums extremely useful - thanks for clarifying the matter for me.

Dear Gilles,
I tested your "corrected" knoppix and it works perfectly right in my case.

Many many thanks.

Gilles, thank you for making the custom ISO image, but it will not boot my computer.
I downloaded the file and got the correct md5sum. Then I burned a CD
and tried to boot it. The system showed "Launching GRUB..." and then hung.

Just as a curiosity, do you have the same problem with Kanotix ?
AFAIK, Kanotix is also using grub as a bootloader.
If Kanotix is working, I can try to make a better CD grub boot
so it will work on more computers. There is always more than one way to do things...
But it is hard for me to fix a problem that I cannot reproduce on my computers.
Best Regards,
Gilles

Hello Gilles, my system boots fine with Kanotix. My hard disk has Windows 2000 on the
first partition and Fedora on the others. Its BIOS is set to boot from CD if available, and
then from the hard drive. Thank you for your interest in my problem.

Hello again, Gilles. I burned a new iso_usb.iso CD, then installed an
old hard disk that contains only one Windows 2000 partition. But my system
still does not boot with your CD.

I also tried booting with no hard disk at all. As before, all I get is the
"starting GRUB..." message. This proves that my boot problem is completely
unrelated to my system's hard disk partitions.

My system has a Gigabyte GA-7N400-L motherboard with an nForce2
chipset, 1500 megabytes of RAM, and an AMD XP3200+ processor.
