I'm a bit gun shy about the GRUB / LILO issues, and being able to use my "daily driver" again. Someone else suggested above that they'd had a bit of a hassle with GRUB initially also.
You don't have to install LILO or GRUB right away because you can start the installed system with the VL CD. At the first screen's prompt you type:
linux root /dev/hdb1 ro
Of course, you change /dev/hdb1 so that it points to the partition on which you installed VectorLinux.
So if you want to use your "daily driver," you'd just start it as you do now. If you want to use VL, you'd boot with the installation CD and use the command above. This way of starting VL gives you time to fix up the boot loader to your liking and to ask for some help if you're not sure about something.
I use LILO. I've never been able to get my mind around GRUB, even though I've read many explanations.
One other concern I have is that Vector seems to only see a small portion of my 4G. I know most 32-bit distros do this, but I've never been sure why since they should be able to address 4G of memory, no? Is there any plan for a 64-bit version, or am I locking myself into the 32-bit world if I fall in love with Vector?
32-bit operating systems can't address the full 4 gigs of RAM. The limit is about 3.5 gigs. We just had a little discussion of this on the forum recently and someone explained the mathematics of it. However, VL should see much more than a small portion of your 4 gigs. My main desktop has 3 gigs and VL sees all of it.
As for a 64-bit version, I'm sure that day will come but not in the next version. You can follow the discussion starting here:http://www.vectorlinux.com/forum2/index.php?topic=3454.msg21814#msg21814
