Quote from: Bolkonskij: "Could you further elaborate what kind of error it is and what you know about it?"Yes, it's not an error or bug, it's a feature that can cause bootable classic OS installers to fail. But it also has an option to get Toast to do the right thing, and increase your chances of it not having your burn made imperfect as an OS install disc. WRT to classic Mac OS disk images burned to CD blanks, because of occasional Toast failures with CD's either booting or having them refuse to run, I put it down to imaging issues... However, when using another burner such as Imgburn on Windows to burn the same Mac images and they were 100% bootable/installable, I had to think, hang on something is not right here. So, looking into how I burned OS disc images using Toast on a classic Mac system, I discovered a feature that was somewhat obscure in Toast 5, more obscure in Toast 4 and downright obfuscated in Toast 3. I didn't look at earlier Toast offerings. The obscurity is in needing to manually ensure the Boot flag on the image is kept intact before you click Burn. I now approach burning classic OS install discs from image files, when using Toast in a classic Mac OS, by doing this: (Toast 5). - I had used Toast 5 with the 7.6DE image, but the steps involved are similar in earlier classic versions of Toast. 1) Mount the image to be burned onto the Mac's desktop locked (always checking the locked status beforehand). Use Toast to mount the image, if the Virtual CD/DVD Utility fails to mount it. 2) In Toast 4: Choose "Mac Volume" from the pull-down list in the main window (if it isn't already selected). 3) Drag the mounted image's icon into Toast's window, then click the "Data..." button. 4) In the "Select Volume" dialog window which opens, manually check the Bootable box and other options if necessary then click "OK". 5) Click OK to this and then burn the image to CD. The approach for Toast 4 is similar to Toast 5's except on clicking OK after checking the Bootable option you get a nag screen on about how you can only use this disc for your personal use and must have a valid license to proceed. It's alsmost a EULA as you have to click "Agree" to ensure the boot flags remain intact, and Toast does not modify the CD as it is being burned. 6) Clicking OK to the nag, you can then proceed with the burn proper. Toast 3: In version 3's Select Volume window, there's a tiny triangular icon, that you click onto, so it points downwards and reveals the hidden Bootable checkbox option, plus you get the nag screen. I get the feeling that somehow the "Gnomes of Apple" may have played a part in this Toast behavior. If burning classic Mac OS images on OS X - I don't use Toast, as it cannot set that Bootable option. Even though Toast 5 on X retains the Bootable checkbox it will not use it. I don't know if Toast 6 has that option, but it's definitely gone from Toast 7+. |
