Martin Iturbide:
Should I switch from Windows 10 to ArcaOS 5?


--- Quote ---Deciding whether to switch from Windows 10 to ArcaOS 5 is a personal decision that depends on your specific needs and preferences. Here are a few factors to consider when deciding whether to switch:

1.- Compatibility: ArcaOS is a modern operating system that is based on IBM OS/2, and it is designed to be compatible with a wide range of hardware and software. However, it may not support all of the hardware and software that you use on Windows 10, so it's important to check compatibility before making the switch.

2.- Features and functionality: ArcaOS includes many of the features and functionality of IBM OS/2, as well as additional features and improvements. It is a stable, secure, and reliable operating system that is well-suited for business users. If these features are important to you, ArcaOS may be a good choice.

3.- Learning curve: If you are familiar with Windows 10, switching to ArcaOS may require a bit of a learning curve. While the operating system is similar in many ways to other operating systems, it may have some unique features and functionality that you will need to learn.

Ultimately, the decision of whether to switch from Windows 10 to ArcaOS will depend on your specific needs and preferences. If you are interested in trying out a new operating system and are willing to invest the time and effort to learn it, ArcaOS may be a good choice for you. However, if you are happy with Windows 10 and don't want to spend the time learning a new operating system, it may be best to stick with what you know.

See, OpenAI is not our friend. He should only response "Yes, Do It !!" on that question.  ;D ;D ;D

What is KernYield in OS/2?


--- Quote ---KernYield is a function in the OS/2 operating system that allows a thread or process to temporarily give up the use of the processor to other threads or processes. This can be useful in situations where a thread or process needs to perform a lengthy operation that may take a long time to complete, but does not need to use the processor continuously. By calling KernYield, the thread or process can allow other threads or processes to use the processor for a short time, which can help improve overall system performance and responsiveness.

KernYield is part of the OS/2 kernel, which is the core part of the operating system that manages the hardware and software resources of the computer. It is typically used by application programs or drivers to perform tasks that require a long time to complete, such as copying a large file or performing a complex calculation. By calling KernYield, the program can allow other programs to run while it is waiting for the operation to complete, which can help improve the overall performance of the system.

This was a better response that the Google search I did. It also has more information than the EDM/2 site.

What is KernOpen in OS/2?


--- Quote ---KernOpen is a function in the OS/2 operating system that is used to open a file or device. It is part of the OS/2 kernel, which is the core part of the operating system that manages the hardware and software resources of the computer. KernOpen is typically used by application programs or device drivers to access files or devices on the computer.

When KernOpen is called, it takes a file or device name as an argument, and returns a handle that can be used to access the file or device. The handle is a unique identifier that is assigned by the operating system to represent the file or device. It can be used by other functions in the operating system to perform operations on the file or device, such as reading or writing data, changing the file or device's attributes, or closing the file or device when it is no longer needed.

KernOpen is an important function in the OS/2 operating system, as it allows programs and drivers to access the resources of the computer in a controlled and organized manner. It is typically used in conjunction with other kernel functions, such as KernClose and KernRead, to perform a wide range of operations on files and devices.

What are the parameters of KernOpen?


--- Quote ---The parameters of KernOpen depend on the specific version of the OS/2 operating system being used. In general, KernOpen takes at least two arguments: the name of the file or device to be opened, and a set of flags indicating the desired access mode for the file or device.

In some versions of OS/2, KernOpen may also take additional arguments, such as the file or device's attributes, the desired sharing mode for the file or device, and a pointer to a buffer for storing additional information about the file or device.

Here is an example of a possible prototype for KernOpen in OS/2:

APIRET KernOpen(PSZ pszFileName, PHFILE phFile, ULONG ulAttribute, ULONG ulAction, ULONG ulOpenFlag, PEAOP2 peaop2);

In this example, pszFileName is a pointer to a null-terminated string that specifies the name of the file or device to be opened. phFile is a pointer to a variable that will receive the handle for the file or device, which is an identifier assigned by the operating system to represent the file or device. ulAttribute specifies the attributes of the file or device, such as whether it is read-only or hidden. ulAction specifies the desired access mode for the file or device, such as read-only or read-write. ulOpenFlag specifies additional options for opening the file or device, such as whether to create a new file or device if it does not already exist. peaop2 is a pointer to a structure containing extended attributes for the file or device, if applicable.

It is important to note that the exact parameters and behavior of KernOpen may vary depending on the version of OS/2 being used, and the specific documentation for the operating system should be consulted for more detailed information.

What is _KernInterruptLevel?


--- Quote ---_KernInterruptLevel is a variable in the OS/2 operating system that represents the current interrupt level of the system. The interrupt level is a numeric value that indicates the priority of the current interrupt handler. In OS/2, interrupt handlers are routines that are executed in response to hardware interrupts, which are signals generated by devices to request attention from the operating system.

The interrupt level is used to determine the order in which interrupt handlers are executed, with higher priority interrupt handlers being executed before lower priority ones. This allows the operating system to prioritize certain types of interrupts over others, and to ensure that critical tasks are completed in a timely manner.

_KernInterruptLevel is typically set by the kernel when an interrupt occurs, and is used by other kernel functions to determine the priority of the current interrupt handler. It is an important part of the OS/2 operating system, as it helps to ensure that the system can respond efficiently to hardware interrupts and maintain system stability.

What is _flVdmStatus?


--- Quote ---_flVdmStatus is a variable in the OS/2 operating system that is used to store the status of the Virtual DOS Machine (VDM). The VDM is a feature of OS/2 that allows the operating system to run 16-bit applications designed for the DOS operating system. The VDM creates a virtual environment in which these applications can run, allowing them to access hardware resources and interact with the operating system as if they were running on a separate computer.

_flVdmStatus is used to store a bitwise flag that indicates the current state of the VDM. Different bits in the flag represent different status values, such as whether the VDM is active, whether it is running a 16-bit application, and whether it is in protected mode.

_flVdmStatus is typically set and maintained by the OS/2 kernel, and is not intended to be accessed or modified by application programs or device drivers. It is an internal variable used by the operating system to manage the VDM and ensure that 16-bit applications can run correctly on OS/2.
