the format of the ISO's have changed dramatically and the vl-iso script has not been updated.
you can run the gui installer from your installed system and install from ISO's that way though
Found in gui installer what I was looking for in tui installer. Installed successfully
after some adjustments. My system fstab is set to sd* whereas this SOHO version
seems to be still on hd* for which reason I could not boot initially and lilo setting in installer
had to be stopped. In lilo.conf changed for SOHO root=/mnt/VLSOHO/dev/hdc8
and booting went fine.
Got sound and internet connection working after second boot.
Will try kernel 18.104.22.168-smp on SOHO to get sd* set properly.
