Talk:Disk operating system

message: The article now says "In the early days of computing, hard drive space was often limited, so the disk operating system was an extension of the operating system. This component was only loaded if it was needed. Otherwise, disk-access would be limited to low-level operations such as reading and writing disks at the sector-level."  Is that referring to the "early days of computing" in the sense of the 1950's and early-to-mid 1960's, or to the "early days of computing" in the sense of the early days of microcomputing?  DOS/360 was a full OS, not an extension to a base OS, loaded only when needed. Guy Harris 20:50, 21 January 2006 (UTC)
replies: text: This refers to the early days of microcomputing (home computers). I have changed computing to microcomputing in the paragraph you quoted. I have also made more of a distinction between operating-system components called "disk operating systems" and operating systems called "Disk Operating System" (eg. DOS/360).

replies: text: I'm afraid, you are mixing up a few things here. You are talking about Microsoft and MS-DOS, however, the term "DOS" for Disk Operating System long pre-dates the advent of MS-DOS, and was used by many operating systems completely unrelated to MS-DOS at the time (and that's what this article is about). Also, the operating system offered by Microsoft as MS-DOS (and by IBM as PC DOS) had its origins in 86-DOS, an operating system developed by Tim Paterson of Seattle Computer Products (SCP) as a  rudimentary clone of Digital Research's CP/M (aka CP/M-80), but ported to run on 8080/8086 processors (and with two significant differences: a different disk buffer mechanism and the introduction of the FAT12 filesystem), whereas Digital Research's CP/M itself was only available for 8080/Z80 processors. CP/M-86 for 8086/8088 processors was not available when 86-DOS development started in 1979 (still called QDOS at this time), but it was available in 1981 at about the same time as IBM began shipping the IBM PC. If you are interested in the early history of MS-DOS, please make yourself familiar with 86-DOS. --Matthiaspaul (talk) 21:30, 2 January 2012 (UTC)
thread_title:  Dave's Operating System 

message: The introduction defines a disk operating system as one that can use a storage disk, presumably in contrast to punch cards etc. It then claims that "Strictly speaking, this definition does not apply to current generations of operating systems". However, most well-known modern operating systems support storage disks, file systems, booting from such disks etc. In fact, the only exceptions I can think of are embedded operating systems.
Maybe the introduction should be changed to "Strictly speaking, this definition also applies to current generations of operating systems, such as versions of Microsoft Windows in use, but it is almost exclusively used for older generations of operating systems."
