I give up, seriously!
This be another rant...
Seriously, when I was 15, I was so good at Intel/Windows/Linux systems that i was granted the highest-level admin privileges for a business with so many users MS-Outlook's contact-list system couldn't even handle them all. It, literally, stated that there were too many users to load... As I recall, that was something like 30,000.
At the time, I was mostly handling lower-level stuff; loading OS's on new machines, etc.
(SUBRANT: I FINALLY located a blutooth keyboard with an ESC key, so I can use VIM on my goddamned phone, because computers are SHIT these days, and phones are SHITTER... but that's another rant, which is coming soon to a scroll-down near you. Anyhow, this damned keyboard has [forward] DELETE as the BIG button next to "+", as opposed to BACKSPACE, which is a button in the upper-right-corner next to F12... WHAT THE HELL?! I mean, seriously, I must've found myself in hell, no? ESCAPE on my other keyboard is "HOME"... BACKSPACE on this keyboard is FORWARD-DELETE. WHAT THE HELL?!)
Alright, where was I...? OH...
So, for 30 years, computers could boot the exact same way... No joke. You could literally throw a DOS 3.2 boot-floppy from the PC/XT era in my Pentium 4's floppy drive, and... it'd boot... Throw a DOS 6.22 boot/install disk in that same machine, and you could literally install an operating-system from twenty years prior on a hard-disk made twenty years later.
Sure, there may've been a few technicalities, a few limitations... Maybe greater-than 2GB was too much to ask, but I never ran into a case where FDISK wouldn't even detect the dang drive, at all!
And, again. I worked in friggin' IT, in the level of installing friggin' operating-systems on machines of countless-vintages.
Now, somewhere in my college-years, when I thought I'd be getting into research instead of IT, I kinda lost-touch with the ol' computer-state-of-the-art... But, again, the state-of-the-art for the THIRTY years prior was that every new generation of [x86] computers was so much backwards-compatible with the previous generations that all you had to do was plop an older boot-disk into a newer machine and power it up...
Now, I dunno what happened in the less-than-1/4 of that intercompatibility-period that followed my leaving the field, but now I've got TWO damned x86-64 [compatible] machines which won't load WinXP. We're talking less than a decade, here... Nevermind the THREE decades DOS6.22 would load without a hitch. The THREE decades FDISK.EXE would detect your drive, whether it was MFM, IDE, UDMA, or even SATA... Heck, given a decent BIOS or BIOS-extension, DOS would even detect SCSI drives, even in the PC/XT era.
Yet, now, even with a BIOS/UEFI-configuration-setting for SATA's Legacy-mode, nary an OS-Installer-boot-disk I've access to (From WinXP to Win7) will detect the friggin' most important piece of hardware in the machine... the friggin' hard drive.
I'm sick of it.
That's all it boils down to. COMPUTERS ARE STUPID. And the designers, apparently, are getting exponentially stupider every year.
