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

[ruymbeke]

Have downloaded minirt_900.gz in the faint hope that it will somehow lead me to a way of obtaining Knoppix 9.0. Have run into two issues so far.
[GvR] The original minirt is just a small file (932KB) included in the Knoppix DVD (4.36GB) that is used during the boot of Linux.

1. whereas your post gives the download size of minirt_900.gz as 23.5MB, Windows file manager gives te size as 63.7 MB (66,866,176 bytes)
[GvR] I just downloaded the file from above link http://s94002264.onlinehome.us/grub/k900/minirt_900.gz and have the correct file size of 24'742'814 bytes.

2. I've searched for the meaning of minirt with Duckduckgo, but the only hit is your post above, so I still have no idea what this file contains or is meant to do
[GvR] The minirt is a init ramdisk loaded by the boot loader at the same time as the Linux kernel that contains add-on boot files necessary to bootstrap Linux.
I customized the original minirt from Klaus Knopper Knoppix 9.0 to add some functionality such as booting from an ISO file and from the network. More precisely I updated the boot script and added some missing Kernel modules to support more network cards and hardware typically used in virtualized environment.

3. I don't have a hash or checksum to test the integrity of the file.

PS. I have a (somewhat) working copy of Knoppix 8.6.1 At least, it boots reliably from flash, but has a fatal flaw it shares with the last six or more versions - Synaptic doesn't work, and I haven't found a way to fix or replace its function. So there is no way to install or update any apps, including virus signatures for Clamv.

I've also been unable to use my desktop monitor with any variants of Knoppix 7.xxx or 8.xxx (the display will not size to fit, so no functions are accessible via gui) and am forced to use my laptop's screen. This is why I keep looking for the latest version, in the faint hope that these issues will have been fixed.
[GvR] Did you try the kernel boot Cheatcodes ?

[GvR] I just downloaded the file from above link http://s94002264.onlinehome.us/grub/k900/minirt_900.gz and have the correct file size of 24'742'814 bytes.

I just downloaded it again from your link, and got a file exactly the same size as before. I made a screensave of the directory entries for both files, showing the time of download and the file size for both, but I don't seem to have an upload option. It's "65,299KB"

[GvR] Please find here the MD5: 9d150bac17e1598391d0c3bfeb9c1123 *minirt_900.gz

Thanks for your explanation and the MD5 sum. I just checked both downloads in Windows and both showed the MD5 hash:

[GvR] Please see this post: http://knoppix.net/forum/threads/450...l=1#post189973

Thanks, I spent many hours when 8.6.1 first became available for download, trying to make this fix work using VIM, but without success.

I'm not sure. It's been a long time since I last played with Knoppix, but I still have fond memories of the time when it was user friendly. Still, the display is a minor problem, compared to the impossibility of installing or updating applications.

Anyway, thanks for your attention. I guess I'll wait for Knoppix 9.x in the hope it will work for me, finally. And maybe then I can also download a properly sized version of your minirt-900 and see how it works.

I went back and downloaded the above file from the same location a second time, only this time I did in while running Knoppix (the first time I downloaded it while running Windows). This time I got the correct MD5 hash. Have never seen this happen before...

BTW, I downloaded the Knoppix 9.1 DVD with Windows yesterday, and just now checked the sha1 and md5 codes, and both are correct.

Hello,
Please find below the latest Knoppix 9.1 minirt for nfs, cifs, nvme and iso boots (32 & 64):
http://s94002264.onlinehome.us/grub/k910/minirt_910.gz (24.8MB, Md5: 558825ccd98bb32148ac54a16e015861)
As usual feedback is always welcome.
Best Regards,
Gilles

PS: the VMware tools 10.3.10-12406962 cloop file I created for Knoppix 9.0 also work for 9.1 as there is no kernel module involved.

Yesterday I downloaded the new minirt910.gz under Windows 8.1 using the Opera browser. As happened with version 90, the download failed the md5 checksum and was almost 3X the byte count expected. I then booted up Knoppix 8.6.1 and downloaded the file again but using Firefox (as I don't have Opera installed in Knoppix). Windows gave the right md5 sum for this download, and the byte count was as expected. Finally, I downloaded the file a third time, this time again under Windows, but using the Firefox browser. This download had the same byte count and the same (correct) md5 sum as the download made under Knoppix. I should probably add that I was running Opera in VP mode (as I am now), but there were no error messages or any other indication of a problem during the download.

I prepared a screensave of the three properties showing the size of the failed Opera download and the correct checksums of the two Firefox downloads, but couldn't figure out how to upload them. The only icon for inserting an image asks for a URL. Is it just that I don't have enough seniority to upload images from my hard drive, or is this a universal restriction? I don't have a website anymore, so this restriction will make it hard for me to display problems via screensaves.

The size Windows gives for the Opera download is 67.5 MB (70,810,112 bytes), while the other two are 24.8 MB (26,104,504 bytes)

I'm still looking forward to installing Knoppix 9.1 (while also trying to secure a copy of 9.2 from Linux-Magazine), after which I hope to discover how to install and use minirt910.

Thanks,

otro
