Did you also update os2ldr? If not you probably should. It should be in the same package.
Yes. The readme did not mention any conditions under which I should not.
The 14.85_w4 kernel package has a CLOCK01.SYS than the one that came with FP15 and 14.62_w4, but the 104a_uni package did not have a CLOCK01.SYS. Which should I use, if it even matters?
My CPU is a i7 (motherboard chipset is Intel x58), but I have not yet tried to find out what OS/2 sees it as. Would OS/2 think it is just a very fast Pentium 3?
As for a OS/2 browser, I now have the Mozilla trio going (though Netscape, Opera, and WebExplorer are still installed).
