Hi again Ben
Here's the scoop: I have just finished a few hours worth of time wasting
with HP support in which we finally identified that two exclamation marks in
the primary and secondary IDE dual FIFO position in device manager probably
means that the hard drive controller on the mobo is on its way out, That
coupled with insertion of another hard drive with a working Windows 95
installation on it which shows the same error on the Primary IDE in IT'S
device manager. Although you were right about the memory. When I put new
Kingston memory in which I got from Kinsgton for this purpose, the unit
configured itself as you said it would and started working properly BUT
problems with the mobo cropped up within a week or so of use.
This is a smallish computer which seems to have a Hawk (or an Asus?)
motherboard.
Do you happen to know which other motherboards I can change this for in
order to get it working, possibly with an upgraded system? I suspect that
any Pentium 11 slot system wouldnt physically fit into this size box but am
I stuck with an under 500 MHz celeron system? (in which case this isn't SO
disastrous as such a mobo might be quite inexpensive AND I already have a
400 as well as a 466 Celeron processor) Or is the Pavilion mobo some type
of special design to get it into this size box?
