Hi, unfortunately I'm using an old SCSI-adapter (Tekram 390UF). The necessary module -ncr53c8xx.ko or sym53c8xx.ko - isn't included in the kernel modules. Is there a workaround to load the module ncr53c8xx or the sym53c8xx on boot? Can I use any precompiled module for a 2.6-kernel?

Hi,
I am making a LiveCD (of my work on localization) based on knoppix. The problem i have with Knoppix-installer is as follows. When i INSTALL knoppix, the installer just ignores all the other OS installations on the hard disk and creates a Grub menu that contains just the new installation.

I have made some changes to the install script boot-tools.bm so that it scans hard disk partitions for other installations and make entries for them in the new Grum menu. Its not tested.

I would like to know if there would be any improvements to knoppix-installer in the near future related to this.

Diff (-pu) follows..
