Emacs is a cross-platform client with the potential to read epub files. The client has support for Lisp libraries, such as for reading epub and pdf files.

One test is to run dosbox-x configured with normal core and segment limits active. It should log the segment limit events. If the segment limit checking is on cs/ds, then another option is to link against hdpmi, if possible, or test with djgpp_nearptr_enable.

In the transcendental test, a 1993 version of MCPDIAG seems to make comparisons between values of PI under two different rounding modes. It loads a log value first from the fpu and then loads these values of PI for the comparison. The fpu status word is compared to a value in memory. The program has …

It is not recommended, but it is possible to install Windows 95 as a guest OS. Another option is to test in Windows 3.1 while in 32-bit mode, but that is not likely to work.

I think so. Given the commit is reversed and the cpu=8086, then it seems reasonable to return to the following instruction for now. I would verify that the registers in idiv are handled correctly, too. I think any change should be attached to 8086, until more is known of the other cpu types. This …
