Programming / Re: Trim command
« on: January 28, 2020, 10:24:29 pm »
Maybe trimming support was introduced in NTFS and FAT32 with later WinXP service packs?
You cannot trim if you don't know what sectors are used or not.
It was introduced in a Vista service pack, and initially at the least only for NTFS, no idea if it is supported in xFATx by MS. It is still a manual process on NFTS by the way, the OS does not trim the drive unless you ask it.

P.S. It is not just SSD's, shingled hard drives from WD and Toshiba also support the Trim command, makes sense on a shingled drive if you think about it. The WD shingled drives are usually large "archive" drives, while Toshiba shingled drives are usually small budget 2.5 external drives.

If a tool is used,then the FS will still need explicit support for trimming (knowing or finding the blocks to trim).

No, witness the WinXP era NTFS/FAT32 TRIM tools supplied by the likes of Samsung

Setup & Installation / Re: Airboot & GPT
« on: January 25, 2020, 08:01:30 pm »
On a system I have two hdd's, one MBR with ArcaOS and one GPT with Win10. Airboot skips GPT disks so it can't boot Win10.
AFAIK the GPT disk has to be converted to MBR for Airboot to see it. Has anyone tried EaseUS Partition Master which claim to keep all data/partitioning on the GPT disk intact, or does anyone have another solution?

I might be misunderstanding this but why do you need to control the boot on the GPT disk via airboot? Why do you not simply use the boot manager built into the UEFI/BIOS and choose GPT/UEFI or BIOS/MBR on startup as needed?

Hardware / Re: Panasonic Toughbook CF-19

Tried to look if someone has had success with Toughbooks ... Specifically Toughbook CF-19 MK3 SU9300. To my eyes it seems that ArcaOS should run without a problem on this machine?

Not with this specific model, but apart from possible BIOS issues like the poster above encountered, the hardware on the MkIII is bog standard and should not create any major issues for the OS.

And cheat I will! Big time and as nerdy as I can: I have already prepared a VM with ArcaOS and hard drive and RAM size as it is buit in the notebook. Also HDD type is IDE in my case. Then I`ve created a disk image with Norton Ghost, and told it to split images into 80 MB pieces. (Done that today.)

Tomorrow I will copy these image pieces to Iomega ZIP100 disks via IDE_ZIP100. Then attaching the Toughbook to it`s docking station (since that one comes with LPT support) Then booting Norton Ghost from floppy on the Toughbook and with the help of an Iomega ZIP100_LPT I will then restore the images onto the Toughbook CF-M34 MK1. So far the plan..


That is a bit convoluted, why not just use DFSee to convert and copy the VM file to the IDE?

Programming / Re: Porting Lilypond to OS/2 - eCS - Arca Noae
« on: November 06, 2019, 09:57:51 am »
Given that LilyPond is more of an engraving program than a traditional notation program and thus not very user friendly would something like MuseScore not make more sense? Or does that have even more dependencies?

BTW. For those with not very advanced needs when it comes to notation, old versions of Personal Composer run fine under OS/2, 16 bit version under WinOS/2 and 32 bit versions PE'ised.

Bonus question: Does anyone remember where the SmartSuite updates (to 1.7.2 and 1.7.3) are located?

ftp://ftp.software.ibm.com/software/lotus/fixes/SmartSuite/

The Lotus FTP site is also still there if you access it via FTP, the HTML front end has been removed however and points to an IBM APAR database

Setup & Installation / Re: How to convert a GPT disk with Win10 to MBR
« on: October 14, 2019, 01:50:34 pm »
I don't want to loose the Win10 installation. How can I convert the disk to MBR so I can add some OS/2 partitions?

This may not be of any help to your use case (laptops with only one drive bay etc), but my preferred way of doing this is to keep it as simple as possible by buying one of those 20 euro 120 gb SSDs from China on ebay et.al. and using this as a MBR drive while keeping the windows drive as GUID. This gives me the added bonus of being able to skip using boot managers unless I want to have multiple OS/2 installs on the MBR drive, as I simply use the F10 (F11/F12 or whatever) boot selection as an alternative, if you choose EFI boot the UEFI bootloader only initially sees the GUID drive even though Windows will see that drive after initial boot, while if you choose the BIOS emulation boot the GUID drive gets ignored.

Similarly during install I simply boot the CD drive in either EFI or BIOS mode using the Fxx key depending on which OS I want to install, etc.

Storage / Re: ArcaPS 5.0.4 install only sees 1 hard drive
« on: October 06, 2019, 01:59:39 am »
If there is no AHCI driver in your eCS setup then I am very surprised that you have a working system. 

I think he is talking about two different systems, his current ArcaOS system and an older eCS based system. Remember that eCS 2.0 had AHCI as an optional install.

The FTP server is still around so there is no need for an archive.org link, just ftp://service.boulder.ibm.com/ps/products/os2/fixes/v3.0warp/english-us/warpinst/warpinst.exe

If you are installing from diskettes, remember that the boot diskettes will be FAT, but the rest will be XDF format, not FAT. It is possible that the VBox diskette emulation won't work with XDF.

It does work with XDF, it emulates a floppy drive rather than an FS.

I have a working model of the Data General One.

I misread this as a Data General Nova, and was for about five seconds ... very impressed ...

Setup & Installation / Re: Warp 3 with WINOS2
« on: September 10, 2019, 03:44:51 pm »
There were basically 4 versions of Warp 3 released, one with WInOS/2 built in commonly referred to as "Blue Spine" and a cheaper option called "Red Spine" that installed onto a system that already had DOS/Windows 3.x system installed and converted that into a WinOS/2 system, it allowed you to save money by not paying twice for the DOS/Win license fees. Later there was "OS/2 Connect" which usually came bundled with WinOS/2 but could be had in a WinOS/2 less configuration at the least for corporate customers.

It looks like you have installed Red Spine, which simply does not have WinOS/2 ...

It is possible to install WinOS/2 after a fashion by simply getting hold of a Blue Spine CD and installing it from there, it was also possible to install Win 3.x and hook it up to Red Spine after the install of the latter, but as it is a quarter of a century since I last did that, my memory of how that was done is a bit faded ...

And portin RUST to OS/2 is absolutely impossible?

Personally I think it has been a bad idea to come up with such a programming language. Many legacy systems won't get Firefox releases anymore because of that... For example TenFourFox for PowerPC Macs is now doomed.

It is not impossible to port the rust compiler, but it is quite a big project and the only use for it really is for the Mozilla ecosystem, we have had problems maintaining much more popular programming tools in the past due to a lack of available programming talent and/or programmers willing/able to give up their free time to do maintenance  them, so focusing what little resources the community has on it will bring only limited amount of software to the platform.

The language features are also strangely old fashioned with lack of memory management (optional or otherwise) and modularity, especially given that the main problems associated with Mozilla browsers in the past have been related to memory leaks, the lack of a modularity is a pain since the rust toolchain is terribly slow making GGC seem fast by comparison. It would in its current state also need redesigning for use on OS/2, as it stands now it is too memory hungry, in fact has not possible to build the toolchain on 32 bit systems since 2014 (modularity would help a lot with this), although this is a language implementation issue and not a technical issue, i.e. it is perfectly possible to create or modify a rust compiler that works on 32 bit systems, but it will add considerably to the effort needed to port it.

The odd thing about rust while it is indeed a safer language than C++ and this is touted by Mozilla as the main reason for its existence, it is still not a safe language, making it yet another safeish functional language variant of which there are already a few thousands. It is a bit perplexing why mozilla choose to invent a new language that sports no new features rather than using an existing language and toolchain ....

Applications / Re: WordPerfect for Windows 6.1 OS/2 tools
« on: August 28, 2019, 04:48:10 am »
It will install under ArcaOS and eCS, but it will only install reliably onto the C drive, and only on some file systems, so no JFS. It may also need the "large disk fix" during install, but it works fine without it.

I installed on e: (no C: drive in the system at the time) onto an all JFS system.  The only issue I really ran into was that the installer can only handle 512M of memory.

As I mentioned before, this was not an installer issue, I may not have been clear in my first post
