Something Happened
My first experience with the Windows 10 media creation tool was, in a word, terrible. After 20 minutes or so of downloading, the tool told me that “Something happened” and the only option was to exit. That’s probably what passes … Continue reading

Solaris 2.6, 7, and 8 Crashes on Pentium 4 and Later
A blog reader recently pointed to an interesting problem which affects older Solaris releases on certain systems. The symptoms (crash/reboot) may at first glance look like the previously described problem which affected Solaris 2.5.1 and 2.6, but both the cause and … Continue reading

Demented Board
Last week I encountered a problem that I have never seen before with a recently acquired Socket 7 motherboard. The board was a Gigabyte GA-586HX (Rev. 1.58), a relatively uninteresting older Socket 7 board based on the well-regarded Intel 430HX … Continue reading

OS/2 Kernel Debugger and MVDM Interrupts
While working on an unrelated problem, I noticed a strange behavior of one of my OS/2 VMs running OS/2 Warp 4.52. To cut a long story short, if an unhandled floating-point exception occurred in a DOS window (VDM, or Virtual … Continue reading

Timing In Software Is Too Hard?
I recently attempted to install RedHat Linux 3.0.3 (that’s the one from 1996, not RHEL 3.0) in VirtualBox. I thought I’d use the BusLogic SCSI emulation and the newer 1.3.57 Linux kernel. It did not work at all. The problem … Continue reading
