I had an AMD 486DX-40 system with two VLB slots. I had both VLB graphics and multi-I/O. Before the Pentium era, a motherboard didn't usually have all the basic I/O on it, so you had to buy a card with serial, parallel, and usually an IDE controller on it. Anyway, the second most annoying thing with VLB is that it ran at your FSB speed, so if you had a 25 MHz FSB you could have three cards, 33 MHz you could have two. I had 40, so I was only supposed to have one. It was surprisingly stable, but when I had the occasional video glitch I understood why it happened and could deal. It got better when I dumped the Computer Shopper white-box special for a DX2/80 with a decent ASUS board.
The most annoying thing with VLB being, of course, that every card was almost full-length because the VLB part sat behind the ISA slot. They popped out all the time.
It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
