ZMV ON WINDOWS!?? [NOT CLICKBAIT]

    Hello netizens. I use Windows now, which means I have to use PowerShell. It's actually pretty neat once you get past the bizarre Verb-Noun command format.

    But, this means I can't use such great features as zmv, which I wrote about in a previous blog post. (I spent five minutes thinking of funny ways to ridicule the fact that I'm not linking to that blog post here but couldn't think of anything worthwhile.)

    Or can I? Well, duh, of course I can. zmv is just a funky little function. I can make my own damn functions on Windows.

    Let's use my previous example of renaming "Artist name - Album title - Track # Track name.flac" to "Artist/Album/# Track.flac" — SHIT, I mean "Artist\Album\# Track.flac". Sorry Gates.

    BEHOLD: zmv for Windows.

Get-ChildItem . | Rename-Item -NewName { $_.Name -replace '^(.*) - (.*) - (.*)','$1\$2\$3' }

    It's a bit more complicated, sure, but it works. Thanks, StackOverflow!

    (Really this series of blog posts is just me learning regex but that doesn't mean I can't look cool while doing it.)



    P.S. While figuring out how to pick PowerShell's background color, I learned that Microsoft PowerToys has a tool for doing regex renames with a fancy GUI, called PowerRename. Freakin awesome!!


    Only problem is that it's not integrated with Windows 11's new context menu (yet?)

Curse of the Apple Thunderbolt Display

Hey all. This is a bit of an update to my previous post, detailing my attempts to get an Apple Thunderbolt Display working with my GIGABYTE Z390 DESIGNARE motherboard. (By the way, it's pronounced with a hard "g" and "a" - not like "designer.") I ordered some replacement PCIe 6-pin to 8-pin adapters, so now I'm able to use the GPU with the required DisplayPort port.

After having flashed the modified Thunderbolt firmware, I expected the Thunderbolt Display to power on and work just fine, at least after reaching the Linux desktop environment (my hopes weren't too high for the preboot environment, i.e. the BIOS menu). Unfortunately, there was still no video output to the display.

However! Using `boltctl`, I was able to see that the Thunderbolt Display was, indeed, detected by Linux! This is an improvement over before, where `boltctl monitor` was able to detect something being (un)plugged, but nothing more. I am now able to connect USB drives to the back of the display, and have them recognized natively in Linux. How wonderful... though obviously not ideal.

I did some more searching, and just a few days ago, the thread containing the custom Thunderbolt firmware was updated with details on an experiment to get Thunderbolt displays to work "during BIOS and OpenCore." In layman's terms, this means the folks over at tonymacx86.com are working on getting the Apple Thunderbolt Display working in the preboot environment of the Z390 DESIGNARE! (and its cousins)

Perhaps this was the key to getting my Thunderbolt Display working with my own Linux setup?

I made a reply to the post, showing my interest in this development, and telling them I was a Linux user who owns the same motherboard and wishes to get their own Apple Thunderbolt Display working with it. I asked if there was anything I could do to help.

In response, they removed my post, stating it was "offtopic" and to "best find a linux thread."

What a bunch of... knuckleheads.

Regardless, this is an exciting development! Hopefully something good comes out of it. Otherwise I might have to sell my Apple Thunderbolt Display and buy a better, more compatible, and probably cheaper display. Oh woe.

Z390 DESIGNARE Thunderbolt ROM Flashing

Hey all. I bought an Apple Thunderbolt Display to go with my non-Apple desktop computer because I am stupid.

It didn't work, obviously. Who would have guessed the Apple display wouldn't work with non-Apple hardware! (I say, having created multiple hackintoshes.)

So I did some reading. Turns out this has been an issue for years. After quite a bit of searching, I read that one person had success after flashing a custom Thunderbolt firmware.

After some "trial and error," including breaking a SOIC8 clip, I finally managed to get this "custom firmware" flashed to my Z390 DESIGNARE.

(EDIT: Oh yeah, I should mention. `flashrom` wasn't able to detect the ROM with just the SOIC8 clip attached, nor with Ethernet attached as well. I had to plug the ATX power cable in, and turn the PSU on (though not the PC). I also kept the Ethernet cables plugged in. Then I was able to read the chip and successfully flash the custom firmware.)

But, you see, the Z390 requires a DisplayPort input from a dedicated GPU to use a display over Thunderbolt - or an iGPU, which I do not have.

The GPU I was using with the DisplayPort port required for that recently became no longer viable, as the PCIe 6-pin to 8-pin adapter I was using burned itself up.

Go figure.

Install Mac OS X from a USB drive on a PowerPC-based Mac

When nothing else worked when trying to install Mac OS X Leopard onto my PowerBook G4 1.67GHz without the original installation DVD, here's what eventually did.

What you'll need

  • PowerPC-based Mac you want to install OS X on by using a USB drive
  • ...USB drive (16GB or more in capacity; 8GB might work, but come on, it's 2020)
  • Second old Mac that already boots Mac OS X Leopard (other versions may work, but are untested. All I know is that my macOS Catalina hackintosh did NOT work)

Part 1: Preparing the disk image for restore

  1. Boot up your second old Mac running Mac OS X Leopard
  2. Download #31 (Leopard_10_5_4.dmg_.zip) from here and extract the DMG
  3. Scan the DMG for restore using Disk Utility ("Images" -> "Scan Image For Restore...")
  4. Lock the DMG (right-click -> "Get Info" -> check "Locked")

Part 2: Restoring the disk image to the USB

  1. Format your USB as "Mac OS Extended (Journaled)" using the "Apple Partition Map" using Disk Utility
  2. Restore the DMG to your USB using Disk Utility, making sure you check "Erase destination" (open the Restore tab, drag and drop the DMG to the "Source" field, drop and drop the partition you formatted in Part2Step1 to the "Destination" field)
  3. Eject your USB drive and plug it into the PowerPC-based Mac you want to install OS X on

Part 3: Installing Mac OS X (okay kids, this is where it gets complicated - mostly copy/pasted from here; follow that if this doesn't work for some reason)

  1.  Boot your PowerPC-based Mac into OpenFirmware (power it down and hold Command + Option + O + F while powering it back up)
  2. Run dev / ls and look for the entry with "/disk@1" at the end of it (in my case "usb@1b,1")
  3. Run devalias and look for the entry with the text you found in Part3Step2 at the end of it (in my case "usb0")
  4. Run dir text_from_Part3Step3/disk@1:3,\System\Library\CoreServices (a.k.a. dir usb0/disk@1:3...) and make sure the entry that contains "BootX" also contains "tbxi" (if it doesn't, panic!)
  5. Run boot text_from_Part3Step3/disk@1:3,\System\Library\CoreServices\BootX (a.k.a. boot usb0/disk@1:3...)
  6. You should see a little spinner, then some white-on-grey text, and finally the Apple logo. Congratulations, you've successfully booted your accursed PowerPC Mac from a USB drive! The installation process is the same from here on out as if you were booting from an official Mac OS X Install DVD.

`zmv` Is Awesome

    BEHOLD! I have awaken from my year-long slumber to grace ye feeble peasants with glorious and other such wondrous things.

    Today, I'd like to shed light on a rather interesting little program: `zmv`. Included with the Z shell, or "zsh", `zmv` allows the user to move files and folders neatly about by following simple-to-use patterns. For example, let's say I've just downloaded an album off of LimeWire with its files in the format of "Artist name - Album title - Track # Track name.flac". It would be rather time-consuming to individually rename each and every file to the desired format of "Artist/Album/# Track.flac", no?

    With `zmv`, I simply need to run `zmv '(*) - (*) - (*)' '$1/$2/$3'`, and shabam-a-lama! My files have moved to perfectly organized directories and subdirectories. How wonderful! How superb!

    And with that, I'm off again. See you all in 2021, I suppose.

Mac OS X Install DVD 10.6 [10A432] - Two Different ISOs?

I'm compiling a collection of all Mac OS X installers ever released. I recently hit a roadblock when I found that my Snow Leopard build 10A432 ISO matched some checksums online, but not others.
So, I downloaded a second ISO, which matched the checksums the original ISO did not. This was a bit concerning, so I recursively compared the files of each DVD with Meld. One, single file was different.

/Instructions.localized/Installation Instructions.app/Contents/Resources/French.lproj/Instructions d’installation.pdf

This is the French translation of the Mac OS X installation manual. It turns out, one DVD still had the 10.5 Leopard variation, while the other had the 10.6 Snow Leopard variation. I guess somebody at Apple was fired on Snow Leopard's launch day.

Checksums of ISO with 10.5 Leopard "Instructions d'installation.pdf":
MD5: 8bce5139afaaa5a8fcda213edf5202b1
SHA-1: 41eca20763eb74c3e23f0bebc36095520e187dc1

Checksums of ISO with 10.6 Snow Leopard "Instructions d'installation.pdf":
MD5: e26826cc68281aa581cc181483bd232d

Various Nokia RM-496 Firmwares

I've amassed some Nokia RM-496 / Nokia XpressMusic 5130 firmwares. I tried uploading them to cpkb.org to replace some broken links, but their account creation system is broken (and probably has been since 2016). Obviously, Blogger is the next best file sharing site. Here are the firmwares in question (plus some other stuff): https://drive.google.com/open?id=1WSLGXezgi9h21tC2_hQ2NSBwMfpEDm_r
They're on my Google Drive, which shouldn't ever go down - but if it does, I think we have bigger problems than a lack of very specific Nokia firmware from 2009.

List of files as of 2019-07-10:

I had to type that list out by hand (Google Drive won't let me select text), and manually hyperlink each file, and pay some shady file hosting website £2.00 for most of the files, and manually request for this webpage to be indexed by Google. So you better thank me!

EDIT: Well, well, well. I ran out of space on my Google Drive. The above files can now be found on Mega: https://mega.nz/folder/0oE3yCra#WDaIRvI_DGi7Tn-jqT-qcw

If you have any questions, leave a comment, and here's hoping Google sends me a notification for it.
