A first problem appeared...
(But before I want to say that this pc was not new to Linux, in past I was able to install SUSE 7.0 with good results - but that times for me Linux was just a word...)
So, let's proceed.
The computer is able to boot VL 5.9 STL GOLD CD but after the first screen the setup live system goes kernel panic
when tries to unpack the initial ramdisk:
- invalid compressed format (err=1)
As soon I hope to have some time to investigate; but for me the problem is that the boot device is the CDRW not CDROM. I remember that in past CD burned with some device was not read correctly by devices of other constructors
(the VL CD was burn with the multifunctional Optical Device of Sony VAIO VGN-FZ21M;
for the old pc device see the first post).
So before pick the screwdriver, I hope the old BIOS allows me to change the boot order from the CDRW to the CDROM.
But, as always, there's other things to try: other live cd, the old SUSE 7.0 Disk 1 and, in general, other bootable Linux CD.But I'm almost sure that using CDROM over the CDRW will solve the problem.
