Re: [Freedos-devel] FreeDOS 1.4-GM

Hi Jim, as the error messages are about exception 07, device not available, all refer to basically the same code address and one of them shows the machine code to be DB E3 which stands for FNINIT, this does indeed look very much like an app which blindly assumes some FPU (floating point unit) to b

Re: [Freedos-devel] FreeDOS 1.4-GM

Tested the floppy installer in 86Box with an 80286 machine, the "[ISA] MR BIOS 286 clone" board (because I like having a BIOS setup menu and a PC/AT doesn't have one) with a 1200KB 5.25" floppy drive and a 1024:16:63 (504 MB) IDE hard drive. The readme says an EGA is required, so I intentional

Re: [Freedos-devel] FreeDOS 1.4-GM

(programs are below) I did a few more tests and this is not a regression. OpenWatcom FORTRAN also doesn't work in FreeDOS 1.3 on the Pocket386. (Although OpenWatcom C does work with FreeDOS 1.3 on the Pocket386.) Config 1: Reinstalled with FreeDOS 1.3 -- base system, then installed Watcomf and Wa

Ben Russell said today: > because I like having a BIOS setup > menu and a PC/AT doesn't have one I did not use many PC/ATs, but all those I used had a BIOS setup menu. AFAIR, it was the XTs and earlier that did not have a setup menu, because they did not have non-volatile RAM. I don't k

Re: [Freedos-devel] FreeDOS 1.4-GM

Did a few more experiments: I think the problem is the OpenWatcom DOS4gw. I can't compile with either OpenWatcom C or OpenWatcom FORTRAN (but I can compile fine with Turbo C). I get a stack trace but it was late and I needed to go to bed so I didn't capture it. I also tried booting without fdconfig

Re: [Freedos-devel] FreeDOS 1.4-GM

It would be great for others to test this too. I'll also try it again and see if it was just a poorly timed hang—the battery died shortly afterwards, so could be something with that, but I doubt it. I am not too concerned about this one issue because: 1. It works on QEMU, and I'm sure works on ot

Re: [Freedos-devel] FreeDOS 1.4-GM

I'll do some tests on that tomorrow if it is really tied to the absence of a co-proc. Considering that Fortran was originally meant to be a math heavy language it might just as well be. Cheers, Danilo On Tue, 1 Apr 2025 at 21:30, Jim Hall via Freedos-devel wrote: > > I've installed it on both my

Re: [Freedos-devel] FreeDOS 1.4-GM

I've installed it on both my QEMU instance and on my Pocket386 computer. So far, it's running well. My only issue is that the OpenWatcom FORTRAN 77 compiler isn't able to compile programs on the Pocket386 laptop. But OpenWatcom F77 works fine on QEMU, so this is something to do with the Pocket386'
