Hardware / Large mouse pointer for high resolution desktop ?
« on: January 13, 2019, 12:26:31 am »
Now that I finally succeeded running OS/2 in a VM at 4K resolution, the mouse pointer is very tiny. I use the comet pointer to keep track of it, but it is still quite small. The standard OS/2 mouse object offers different mouse pointer icons, but they are all small.

Is there any software out there that will allow using a larger mouse pointer ? In my Win10 host, also running in 4K, the pointer is large enough.

Hardware / 3 printers in the house - will any of them work with OS/2 ?

I have the following :
- a Brother MFC-L8850CDW all-in-one laser printer (2014 model)
- a Canon Pixma Pro-100 inkjet photo printer (2012 model)
- an Epson Workforce 7110 inkjet photo printer (2014 model)
All of them are networked with Ethernet.

I didn't see any of them listed with ArcaOS CUPS drivers.
Is there any chance of getting one or more to work, and if so, with which driver ?

Hardware / Is there any SCSI PCI Express card supported by OS/2 ?

Some of you will probably recognize my name from the 1990s. I was a fairly active OS/2 user and developer.

I have some important data backed up on DDS-2 / DDS-4 tape which can only be restored with some OS/2 native software . The tape drive is an HP Surestore DAT40e (DDS-4, Ultrawide SCSI-3).
I have eCS 2.1 and the Bakupwiz and GTAR software required.

My problem here is that I had been using a PCI bus SCSI card until now, based on LSI Ultra160 53C1010 chip.
I have 4 PCs in the house. Only two of them still have a legacy PCI slot, but soon to be only one.

1) One is has an Z170-AR motherboard with an Intel 6600k CPU . It runs my home NAS with ZFS under Ubuntu Linux now. The mobo has a single PCI slot. I tried putting the LSI card in it before, but the Symbios BIOS on bootup runs very slow (like, several minutes). I think there is some incompatibility between the Asus BIOS and the LSI SCSI card BIOS. I doubt I would be successful using this SCSI card under OS/2 on that machine to restore my tapes. Installing OS/2 alone, probably. But I need access to the SCSI tape drive.

2) The other has a Gigabyte GA-990FXA-UD3 motherboard with an AMD FX-8120 CPU. I believe I ran eCS on it previously, and it worked with the LSI SCSI card, and I could access the drive. eCS in general however didn't behave well at all with this combo of mobo & CPU : no power management - all fans running 100% . And SMP not working at all. This machine has been my HTPC for 6 years. It's quite loud due to the high wattage CPU.

I'm in the process of replacing it with a Ryzen 2700. However, the new Asus X470 Prime Pro motherboard doesn't have any PCI slot, only PCI Express, so this motherboard will be offline pretty soon, probably in the next 24 hours.

Is there any SCSI card that is PCI Express that has a native driver for OS/2 ? Ideally, I would like to find such a card if one exists.

I have seen some PCI to PCI-E converters like this one :

However, my LSI SCSI card is not low profile. And even if it was, I would probably still run into the BIOS incompatibility with modern chipsets.

If there isn't a current PCI Express SCSI card solution, I will probably buy another case to relocate my GA-990FXA-UD3 board & CPU, and make it a dedicated OS/2 machine, at least temporarily. I can run it on a KVM switch.

If a virtualization option exists that will provide a SCSI interface to the  guest with an OS/2 driver so that it can access the tape drive, I'm open to that also, rather than fiddling with bare metal, but I haven't seen any such thing in Virtualbox.
