Storage / Re: DISKIO - updated version in need of TEST
« on: Today at 01:02:44 am »
Diskio reads tracks and ignores partitions and file systems. Along with the rest of OS/2, it does expect 512 byte sectors but i doubt that matters.

Exactly the same here, power savings on this old Samsung SyncMaster 243T is from less then 75 watts (74?) to 2 watts, which adds up

Hi Andi, so it seems to be a limitation of emulating DVI, makes sense.
As for the screensaver, it might wel work for you now given a recent Panorama.
I'll attach a simple test program, run "panodpms c" to see the capabilities of your system. Panoutil.cmd is a safe way to test, it should turn off your monitor and wait till you press a key and then turn it back on, if it works, then the most recent screensaver will work as well. Note that now a days only on and off make sense with LCD monitors.

Hi Dariusz, I'd guess the DVI to Displayport adapter might work, you'd have to test, might only be available as an active adapter, hopefully simply using USB power. Let us know if you ever try it.

Hardware / Displayport?
« on: August 05, 2022, 07:34:37 am »
So this computer I'm using has a Sandybridge/Ivybridge graphics controller with a VGA and a Displayport ports, monitor has VGA and DVI ports and supports 1920x1200 as its native resolution.
For quite a while I was simply using the VGA connection, everything worked fine but slightly blurry.
Then I came across a Displayport to DVI passive connector so I tried that.
While the graphics were sharper, especially text mode, I came across these limitations. The screensaver would put the monitor to sleep but it would not wake up, forcing a reboot to awaken it. Same with SNAP and Panorama. Nothing I tried helped here, worked fine under Linux, which reported a HDMI connection. The other thing was I tried using Xfree86 using the VESA (VBE) driver, it simply did not find a graphics card at all, which was weird. Works fine with the VGA connector and an older Panorama/SNAP, newer ones seem to have done something to support UEFI where switching back to the WPS fails, a bit of drawing and then a full hang.
Just wondering about others experience with Displayport and OS/2. Perhaps a monitor that supports Displayport would be better, it seems that Displayport falls back to a DVI compatible protocol when used with a passive converter.

I have to say this is a bit of a shame. 20+ years worth of links on the Internet to the Hobbes archive don't work anymore. Several archives on Hobbes also have text files in them referencing other files on Hobbes by filename, which can no longer be searched since most of the names have been changed.

Would have been better to create a new index referencing into the old structure or something. As it is now, I've been using one of the mirrors listed in the main page to find the files with their correct filenames. And I have the original directory structure memorized..

Ah well..

The Hobbes maintainers themselves changed things a couple of years back and broke everything, then they went to HTTPS which also broke all links.
Personally when posting a link in a readme etc I try to use a search term, which helps until Hobbes changes again. Remember it's main purpose is a teaching tool at a university.

Utilities / Re: Text editor

I finally got a newer version of the old vi clone Elvis ( https://github.com/mbert/elvis ) working!

And now inquiring minds will surely like to know how you accomplished that ;)

Looks like it still has OS/2 support, Open Watcom and GCC, both EMX and kLIBC, EMX required for X11 support.
Have to test it, https://github.com/mbert/elvis/blob/master/osos2/Makefile.os2

Is there interest? Basically have to use the VESA driver and all the apps are so old.
The problem with XFree86 is they changed the licensing, making it incompatible with the GPL, which is why everyone moved away.
Looking, it looks like Xorg 6.9 was the last to use the imakefile style of building and still had the OS/2 code in it. With v7 they went to a configure build system, haven't looked to see if OS/2 code was still there but it would be hard to build compatible libs as all functions were exported by ordinal and there was basically a database of ordinals to keep the DLLs backwards compatible.

Applications / Re: DOS version on ArcaOS
« on: July 24, 2022, 07:27:10 pm »
There are DOS 1 programs, DOS v1 was quite different, no directories, FSB's, making it more like CPM.
It is also possible to boot CPM86 on OS/2. Possibly other programs worked around DOS bugs that were then fixed breaking the programs.
Be interesting if FreeDOS could run in a VDM. Potential problems include that it wouldn't have full disk access for implementing long file name support (vfat) and perhaps mouse access.

Is it worth even keeping v3.1 (and 3.2) around? The latest 3.x was 3.3.6, which perhaps should be uploaded to Hobbes, same with 4.x where the latest seems to have been 4.5.0.
BTW, the last release of XFree86 seems to have been 4.8, which I could probably build, it's EMX, need gcc-elf and an EMX unixroot. Probably some of the xorgs from before they ripped out the imake stuff and/or OS/2 code could also probably be built. I don't see the point unless very bored though.

Applications / Re: Path
« on: July 23, 2022, 05:44:44 am »
Generally yes, as long as the directory is on the PATH and DLL requirements are met. Didn't you test?
It does fall down if the program needs to be started in its directory such as Firefox which looks in its working directory for its DLLs.
Can't remember if File Commander needs to find its ini, hlp etc in its current working directory or its program directory, or if PATH is good enough to find them. Hmm testing, it does seem PATH is good enough for fc to find its supporting files.

Hi Chris,
I have a vague memory of some Desktop background BMP's etc causing problems. You might want to move them all out of the way and see if OS2OOOC.DLL still crashes.

Remember that OS/2 and Windows BMP files have differences. Cant remember what they are at present as most of my stuff, including my OS/2 computers are packed up. PMView from memory can save a graphics file to either format, I had to save some Windows BMP files to OS/2 format to use as background images.

Yes, Chris did say,
Quote
Not any of that image, irrespective of whether I saved them as OS/2 1.x or OS/2 2.x (with or without RLE encoding). It just choked.
As did that image as a JPG. I didn't try a number of options here.
Could it be the colour depth? If I get bored I'll try.
However, saving it as a GIF did allow it to work.

And later even 8 bit failed.
File does seem to mostly understand OS/2 bitmaps, failing to get the horizontal size in 2.x ones
Code: [Select]
W:\OS2\BITMAP>file BIGBLU.BMP
BIGBLU.BMP: PC bitmap, OS/2 1.x format, 287 x 287

W:\OS2\BITMAP>file DTOP1680.BMP
DTOP1680.BMP: PC bitmap, OS/2 2.x format, 1680 x 0

W:\OS2\BITMAP>file DTOP1920.BMP
DTOP1920.BMP: PC bitmap, OS/2 2.x format, 1920 x 0

W:\OS2\BITMAP>file GARDEN.BMP
GARDEN.BMP: PC bitmap, OS/2 1.x format, 1024 x 768

Yum install file

Actually it didn't. So back to the gif.  ::)

Strange that the GIF works, I'd expect it to be converted to BMP at some point on the way to being a desktop background anyways.

The Virtual Box approach might work, but it appears that it needs the VBox Exensions. But worth playing with. I've had enough fun with local virtualisation for now... (see my next post).

-Chris

You want to install the additions anyways, mouse, video support (special gradd driver, not SNAP). Shared folders, IIRC, are a bit wonky but work. Just have to be careful about them downgrading libc depending on your setup.

As Neil said, wait for AOS 5.1, install in UEFI mode and use a graphical bootmanager. I use rEFInd for UEFI, works well, graphical so should work for you.
