For BL3 it is 'rc'.

This will run rc and then /bin/sh, which sets the path specified in rc and 
then adds what is in profile to later in the path?  I will experiment with 
this.

I think just sh is doing that because startx worked and profile is what 
put X11R6 on the path.

I did not know that you could release something free and then take it 
back, or is it just that they are not letting people use the newest 
version for free?

2.5.something is the first version where they fixed the bug in the kernel 
that kept cdrecord from working with my CD-ROM drive.  We will see if 
Ubuntu can work with it.  I think they may use some other Cd burning 
program anyway - do you happen to know?

Do you know if we can just snip the wire that replaced the jumper on a 
board which can take either AT or ATX power supply?  A Tyan with 350MHz 
AMD K6-2 just got left on our doorstep as a kit, in a case with AT power 
supply, but hardwired to ATX.  I can test video cards in it once we get it 
working.  We have no extra ATX power supplies.  It has four ISA slots (so 
I can really mess things up with too many IRQs taken).

Do you know why a modem that we just flashed from x2 to x2+v90, which used 
to connect at 31200 with port speed 115200, now won't connect at all with 
that port speed, and with 57600 sometimes connects, but at 28800?  Phoebe 
Micro, so it won't take the USR command to disable X2 (S32=34).
