I unzipped the program files into a directory. I downloaded and extracted the harmonics file

https://flaterco.com/files/xtide/harmonics-dwf-20251228-free.tar.xz

I set and environment variable to the location of my harmonics file

Code: [Select]
set hfile_path=\suntanv6\apps\xtide\dist\harmonics-dwf-20251228-free.tcd
I ran the program, but I now get a message about time zone support.

Code: [Select]
tide -l "Santa Cruz"

Indexing \suntanv6\apps\xtide\dist\harmonics-dwf-20251228-free.tcd...
XTide Fatal Error:  BROKEN_ZONEINFO
Your platform appears to have broken time zone support.  You need to have a
reasonably modern version of the time zone database that is available from
http://www.iana.org/time-zones.

The XTide program shows the tide table for a particular location. It worked for years, but stopped a couple of weeks ago when the harmonics fiie expired.

It's still under development here:
https://flaterco.com/xtide/files.html

But there is no longer any OS/2 version.

Although it is an X program, there is also a command line version, tide.exe, which was more useful for OS/2.

Is there any hope for building the current release; at least the command line version?

Hardware / Re: Video memory cannot be assigned to 32-bit address!

For my Lenovo Thinkpad X13 Gen 2, the "Accessible to system" memory reported by mem /v is 2267 MB

And this is a "ThinkPad Ethernet Extension Adapter Gen 2" I am using for Ethernet. The X13 gen 2 and the T14s gen 2 share a hardware manual, so they are very similar.

I also have the Lenovo Thinkpad USB-C Doc Gen 2, so I plan to learn a lot more about USB support under ArcaOS.

I need to correct my previous post. I changed the BIOS setting for video RAM from 512 MB to 256 MB, and ArcaOS can now run on the computer. The latest MultiMac32-E1000B driver supports the Ethernet port.

A Lenovo adapter is required to connect an Ethernet cable because the laptop is too thin to support a normal Ethernet connection.

I have a Lenovo Thinkpad X13 gen 2, and while I didn't get it to run ArcaOS, I was curious if it could be done.

It can't. (see attachment) Actually, it can. See correction below.

Storage / 4 TB hard drive
« on: December 27, 2025, 02:18:23 am »
The time finally arrived for a hard drive upgrade for my travel laptop. I mostly run ArcaOS, but occasionally Windows 11 for web browsing and hardware support. My ArcaOS computer hosts about 1.5 TB of data. I wanted to build a computer that runs ArcaOS in a VirtualBox session and holds a copy of that data. I backed up my computer, and installed a 4 TB NVMe m.2 2280 SSD. I restored from my backup.

(see attachment)

The backup software I used (EaseUS Partition Master) made the wrong volume type for my ArcaOS volumes, and so I needed to fix that. I was able to make some fresh ArcaOS Type 1 volumes and temporarily assign drive letters to the volumes with the wrong volume type. The new volumes are able to boot ArcaOS.

I extended the Windows boot volume to just over 3 TB, and created a new virtual hard drive to contain my data. I used rsync to bring over the 1.5 TB data to the new virtual hard drive. The virtual hard drive is actually a bit FASTER than JFS running native. It still took a long time to copy 1.5 TB of data.

When I was done, I deleted the volumes with the wrong volume type. This was a mistake, as my Windows 11 volume would no longer boot, failing with UMOUNTABLE_BOOT_VOLUME (0xED). It turns out that Windows boots the Nth volume on the drive, so it could no longer find the boot volume. I made two dummy volumes, and Windows was able to count up to 5 and boot again.

So far, the Virtual ArcaOS works well, and it's nice to have an easy way to share data between OS/2 and Windows 11.

Networking / Re: Network setup for VirtualBox

Further experimentation. First, I say again that on Windows 11, NetBIOS works on adapter 2 as expected.

Setting Promiscuous mode has no effect, as far as I can tell.

Even TCP/IP on Adapter 2 does not work in Linux. I can swap adapter type, it makes no difference. And If I put NetBIOS on Adapter 1, it does work in Linux. But I have to have the adapter in bridged mode, so I have to choose the adapter. That means not supporting WiFi.

This sounds like a bug in VirtualBox. Adapter 2 works in Windows, but not in Linux.

You can make DVD > 2 GB

The following statements extracted from one of my old DVD burning programs.

'@cdattach' DVDletter
'@cdwfmt' DVDletter '/erase'
'@cdcopy' tmpCDroot || '\*.*' DVDletter'\ /s > nul'
'@cdattach' DVDletter '-s'

Networking / Network setup for VirtualBox
« on: December 18, 2025, 01:06:02 am »
I've been using ArcaOS running under VirtualBox running on a Windows 11 host. Setting up the network is pretty confusing.

A laptop has a WiFi card and wired ethernet. I can connect either one to my network. I set up Adapter 1 as an Intel Pro/1000 MT desktop (NAT) so that it can get TCP/IP from either laptop interface.

But I want NetBIOS, too. I don't think I can get that from NAT. NAT is TCP/IP-only as far as I know. So I defined Adapter 2 as PCnet-FAST III (Bridged to the Ethernet interface on the laptop.) That only gives me NetBIOS over Ethernet, but that will be adequate. So far, so good.

But now I move to Linux host, and NetBIOS does not work. In fact, I'm not at all sure any Adapter 2 function works on Linux. Perhaps I should ask over in the VirtualBox forum, but there are more OS/2 experts here.

How are you implementing NetBIOS under VirtualBox?

Storage / Re: Does anyone have a copy of the 386 HPFS Upgrade for WSeB?
« on: November 29, 2025, 03:44:40 pm »
Consider also WebSphere, as long as you have DB2 and Lotus Domino Go Webserver already.

HPFS 386 of course for completeness, but also remember JFS is already there.

FWIW I made an installer for Vslick as a part of my Suntan Special product. It wasn't much. I unzipped a saved installation, modified vslick.sta to reflect the new installation directory, and inserted my license file.

We could hack together a decent WarpIn installation program.

General Discussion / Unfortunate filename choices
« on: November 23, 2025, 08:58:37 pm »
Due to some careless cut and paste, I recently named a file with a leading space. This can make it difficult to manipulate on the command line. I'm sure there are some other non-obvious bad filename choices.

There was not an alpha of PMMail. There was an announcement. It was wrong.

There have been a few bug fixes over the years, and I'll probably do another release. Occasionally I rebuild to make sure I can still do it, and to reset the timebomb.

I have contacted two driver developers about making new OS/2 drivers, and both were positive about it, but both refused to consider a WiFi driver. If you take a close look at the open-source GL.iNet travel routers, it will become clear why that is.

It is a big job, even considering that you have the GL.iNet source code.

Setup & Installation / Clock Syncrhonization under ArcaOS
« on: November 02, 2025, 05:34:18 pm »
ArcaOS uses Clock Synchronization to adjust for Daylight Savings Time (DST) adjustments. The time just changed in my part of the world, and when I sat down at the computer, it was still on DST. So I synchronized manually again this year.

But while I was doing it, I noticed something. ArcaOS is set up to synchronize every 720 minutes. But I get up early, and it's only been 240 minutes since the time changed. I changed the 720 to 180, and I'm going to see if it works next time the time changes, March 8, 2026.
