Hardware / Iomega ZIP 100 IDE
« on: December 30, 2021, 10:48:35 pm »
I have iomega zip 100 with IDE interface. I want to access the disk.
I installed an additional IDE controller and drivers:

Code: [Select]
BASEDEV=DANIS506.ADD /!BIOS /A:0 /BM /U:0 /A:1 /I /V

The system is successfully loaded.
I get a report:

Code: [Select]
R1.8.15      /!BIOS /A:0 /BM /U:0 /A:1 /I /V
            Daniela's Bus Master IDE Driver for OS/2 Version 1.8.15

Port D020/D012, Irq 16, ATAPI, PIO0

0/s: (not present)

However, the drive letter in the system is not assigned and contact the device cannot be applied.

What can be done to get a drive letter in the system?
According to my memories, once a long time, this device worked in the OS / 2 system.

Hardware / USB 12.07 stack - Audio Clicking Issue
« on: August 19, 2020, 01:39:10 pm »
Version 12.07 looks much better. However, the problem with the quality of USB sound has not been fully resolved.
The new version does not lose data anymore, but the sound is choppy. It's like listening to a clipped vinyl record with clicks. Obviously, by the time the playback of the data packet is completed, the next one does not have time to arrive.
Most likely this is a problem in the ECHI driver that they tried to solve. I advise developers to rely on the experience of the 16-bit version. These problems are not there...
