ISO boot from FAT/NTFS/USB (GRUB.exe, grldr from boot.ini)

**ICPUG** · 09-27-2010, 06:29 PM

It took a long time but I have finally got The Poor Man's install of Knoppix 6.3 DVD to boot!

Rymbeke's minirt from Knoppix 6.2.1 WAS OK. The problem lay in the boot codes I used. In previous versions I did not have to specify a screen boot code. I had a look in the isolinux configuration file on the DVD and noticed a reference to vga=791. I tried this on my setup along with the i915.modeset=1 cheatcode and it booted up!

Things are still not fully right as with this setting I cannot see the startup messages or the screen to create the file to enable persistence. This is really strange because when booting from the DVD all is OK.

I have other boot code issues. In previous versions I used lang=uk to get a UK keyboard. With this version if I do that my keyboard doesn't work! If I do not specify a keyboard it boots up and allows me to type with a US keyboard layout. The time zone appears to be US as well since my clock shows time 5 hours behind the time it showed when I had lang=uk.

Of course, these problems are nothing to do with the Poor Man's install so I am happy to report that a Poor Man's Install of Knoppix 6.3 can be achieved on a machine with the Intel 855 chipset.

I read on the Knoppix mailing list that you have done your magic on the version 6.5 Knoppix distributed with Linux Magazine recently.

Would you care to share the revised minirt.gz with us here?

Hi ICPUG,
Here it is: http://s94002264.onlinehome.us/grub/minirt_650a.gz and http://s94002264.onlinehome.us/grub/64_minirt_650a.gz
with some grub menu.lst sample config file. Please provide some feedback...
Hope this helps. Best Regards,
Gilles

PS: To use data persistence on a partition (instead of a loopback file) use data=sdb1 as an example (but please be careful...)
PS2: For ISO boot you need to add the file knoppix.sh (http://s94002264.onlinehome.us/grub/knoppix650.zip) within the same directory as your iso file.

I've done the first test.

I copied the Knoppix and Linux files from the DVD to an NTFS hard drive partition together with minirt_650a.gz. Knoppix 6.5 boots up as well as the DVD. Since 6.4 I've been able to do this with the standard minirt.gz so this is not a great test, It just proves minirt_650a.gz has not broken anything.

What I need to do next is test the capability of booting a iso, but to do that I need to create an iso from the DVD ...

Hi ICPUG,
I forgot to mention that for the ISO boot to work, you need to add the knoppix.sh file within the same directory as your iso file.
Download of the knoppix.sh file: http://s94002264.onlinehome.us/grub/knoppix650.zip
I edited my previous post to add this info (PS2).
Best Regards,
Gilles

Hi Gilles,
Will any of knoppix650.zip or knoppix630.zip work with v. 6.4.4 since they all have different kernel verisons? It is said that version 6.7 is also starting to appear in mirrors, hopefully we will be able to have your modified linux an miniroot.gz files to try.

Hi _yes,
Here it is: http://s94002264.onlinehome.us/grub/k670/minirt_670a.gz and http://s94002264.onlinehome.us/grub/k670/64_minirt_670a.gz
Please provide some feedback... Hope this helps. Best Regards,

I am confused. The underlying file under these links says minirt_650a.gz and 64_minirt_650a.gz

Are the links pointing to the wrong files?

**ruymbeke** · 08-16-2011, 04:54 AM

Hello,
The forum had a very strange behavior...
The "c" version is the correct update: (I also updated the previous post)
http://s94002264.onlinehome.us/grub/k670/minirt_670c.gz
http://s94002264.onlinehome.us/grub/...minirt_670c.gz
