Little details regarding SN #836

  • SpinRite v6.1 Release #3
    Guest:
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

    (You may permanently close this reminder with the 'X' in the upper right.)

Just listened to SN #836.

Here's a couple of items I took note of:
  • Mēris is pronounced Meeris (prolonged e that sounds like an English "eh" but without inflexion). Google Translate has a pronounce translation feature :)

    Google Translate

    Google's service, offered free of charge, instantly translates words, phrases, and web pages between English and over 100 other languages.
    translate.google.com translate.google.com
  • To be precise, IPv6 does not have the ARP protocol. It uses the NDP protocol over ICMPv6.
  • We do have a very used Layer 6 protocol: TLS. It encapsulates HTTP into a TLS packet that's then handled by TCP (HTTP/2 and earlier) or UDP (HTTP/3).
    On the layer 5, there's Remote Procedure Calls.

    I wasn't sure whether TLS would be Layer 5 or Layer 6, so I looked up on Wikipedia, which has a very handy table :) https://en.wikipedia.org/wiki/OSI_model#Comparison_to_other_networking_suites
Keep up the amazing work
