kid2 recovery

Once I hooked up everything from screen to mouse, kid2 wouldn't boot.  I juggled the RAM around a little bit, now both on same-color sockets, then it would still not boot but at least display a BIOS error message on the screen.  So I loaded the "Safe defaults" then "Optimized defaults" (whatever these are) and it worked.
The Windows partition still doesn't work (reboots when I try) but Ubuntu Wily (15.10) is still there.   I had to look a little bit around in order to find a mirror that still had Wily files but then "apt update" worked (except for some ubuntu-security stuff) and I launched "apt dist-upgrade".  That's going to keep it busy for a while.

The only thing that doesn't work right now (in addition to Windows) is the mouse (still a ps/2 ball mouse).  I need to recycle that thing.

• /dev/sda seems to be a single-partition linux disk (mounted at /home) of size 300G, by Seagate
• /dev/sdb is smaller (160 Gb Hitachi) and partitioned as follows:
• sdb1 12 Gb= Windows recovery
• sdb2 80 Gb= Windows (broken), may still contain some data
• sdb3 4,2 Gb= swap
• sdb4 38 Gb= Linux (root)
• CPU is a E2140 @ 1.60 Ghz
• There are 3 free PCI slots
• There's an (unused) IDE interface on the motherboard
• There are USB slots available, looks like 4 USB1 controllers and 1 USB2 controller
• The Realtek Ethernet controller claims Gigabit ethernet compatibility
• There is no built-in graphics card, but an AMD/ATI Radeon is on the PCIe slot
