Even if you can do without, why? Whenever I have a kernel panic, the Wallstreet reboots into 9 on the second partition. I do have Classic on the first partition, but never get it. What will happen to you when you reboot after a kernel panic in Jaguar if you don't have 9 installed? I dunno. Some follow up to the other replies: For diagnostic purposes, you may find it necessary to boot from an older CD or external drive. Regardless of whether you intend to install MacOS 8/9 or not, I consider it highly desirable to install the 9 drivers when you partition. OS X is the only OS which must fit within the first 8 GB. I have Jaguar in my first partition and MacOS 9.2.2 in the second partition and everything runs fine with either system. Note that you may run in to problems if you format your HD to exactly 8.00. I have been unable to get a definitive answer to this question, but be aware that there are two definitions to a GB: 1,000 MB and 1,024 MB (likewise MB vs. KB). Which to use? Using the wrong one can make the difference between wasting space and having a time bomb waiting for you to use those last few sectors. For safety's sake, limit your partition to 7.91 GB. Only one of your DIMMs needs to be low profile. I would love to upgrade to Panther, but in spite of numerous attempts and XPF, I have never succeeded. Indeed, I have never succeeded in booting into X from any external drive or install CD. Others have. YMMV. If you are going to spend more than $150 upgrading, I would seriously consider selling the Wallstreet and getting a newer book which officially supports Panther or Tiger.
