All these systems I have trouble with are in some kind of production use,
so I'm pretty much deadlocked until I happen to be awake at suitable
morning hour to be able to experiment (when they crash during peak hours, I
have to just get them up as fast as possible). I was also trying to read
some boot code source to learn more about this and how it could be worked
around (but I haven't had much time lately).
About the suggested fdisk fix, if C/H/S values are changed wouldn't this
break the partition limits, or are the partitions encoded just as block
offsets?

Install an Intel Plato system in dangerously dedicated mode with BT ISA
controller and replace it with a NCR PCI controller, and it may/will not
boot (too large cylinder number 1040 > 1024, BIOS limit). This is actually
quite weird, as the root partition is about 200Mbytes which should be below
1024 cylinder, no matter what geometry is used. This isn't that serious,
I'll reinstall on another machine and copy the files over and switch the
root disk to see if it fixes the problem. The previously mentioned Plato
to ASUS switch was worse as it was the primary server which can't be kept
down for long, and it takes some time to move services out of it so that I
can start experimenting with it.
