“There was a problem starting C:\Program” “The specified module could not be found.”

Posted by jpluimers on 2019/12/02

If you get this error:

—————————
RunDLL
—————————
There was a problem starting C:\Program

The specified module could not be found.

—————————
OK
—————————

Then it is likely a process trying to run an unquoted path like this:

"C:\Windows\System32\rundll32.exe" C:\Program Files (x86)\ThinkPad\Utilities\PWMTR64V.DLL,PwrMgrBkGndMonitor

Blast from the past: dial-up modem sounds

Posted by jpluimers on 2019/12/02

Because fewer and fewer people have used them in real life: this is how geeks communicated even before the internet era.

Below a series of videos with modem sounds. One as recent?! as 2008 when dial-up was still possible in many places. Now it’s a not just a thing from the past, but an area where mankind learned a lot about signal processing, for which the knowledge is still in use today.

  1. [Wayback/Archive] The Sound of dial-up Internet with dial tones and initial training sequences
  2. [Wayback/Archive] ALL Old Modem Sounds (300 baud to 56K) demonstrating how a Conexant V.92 based soft-modem could create most modem standard used in North America (Bell 103, V.22(bis), V.32(bis), V.34, V.90, and V.92), corresponding to 300 bps, 2400 bps, 14.4K, 33.6K, and 56K.
  3. [Wayback/Archive] Dial Up Modem Handshake Sound – Spectrogram which is a preamble to [Wayback/Archive] absorptions: The sound of the dialup, pictured.

Windows XP Pro won’t boot, safe mode boot hangs at agp440.sys – Microsoft Community

Posted by jpluimers on 2019/12/02

When safe mode is a good thing: [WayBackWindows XP Pro won’t boot, safe mode boot hangs at agp440.sys – Microsoft Community

During the regular boot, after a minute or so on SSD, a legacy Windows XP SP3 machine didn’t reboot.

During safe mode, it hung after loading agp440.sys. Apparently this is a Good Thing ™ as it means that chkdsk is running in the background as the post above explains.

Nice to know!
