Its software acceleration compensates for sub-optimal disk performance to make extensions and control panels load faster. Startup your powerbook faster at airports (and everywhere else!), zap through all those startup icons! Save time each time you startup your Mac! Those seconds spent waiting really add up: Startup Doubler makes startups up to twice faster, depending on the performance of your startup disk and the number of Extensions and Control Panels in your System!
Installation
1 Run the Startup Doubler Installer
2 The SECOND restart will be accelerated, as well as the next ones. The first restart is used to build Startup DoublerÕs data.
3 check my web page http://www.kagi.com/authors/marc/ for the latest version.
System 7 or Mac OS 8 on a color-capable Mac are required, and 8 megabytes of Random Access Memory (RAM).
Note: Turn off any anti-virus software while running the Startup Doubler installer (use the anti-virus software to scan the installer beforehand if needed)
Removal
Please use the Startup Doubler installerÕs Remove button to un-install Startup Doubler from your system.
Using Startup Doubler
After restarting, you may enter your preferences in the control panel.
Checking the Startup Acceleration box enables Startup DoublerÕs innovative acceleration technology. This transparently affects Extensions and Control Panels and makes them load faster.
¥ I recommend you use the Memory control panel to set the disk cache size to at least 1024K on a 32 meg machine, at least 512K on a 16 meg machine, to make startups even faster.
¥ hold down the Shift key at startup to bypass Startup Doubler if needed. This will also bypass loading all other extensions and control panels.
¥ if you have many (50+) extensions, Startup DoublerÕs optimal performance will probably be reached after a few restarts, as it adapts to your system.
¥ disk checks after a crash arenÕt accelerated. Upgrade to System 7.6.1 or later to get faster disk checking.
Compatibility
A lot of time goes into making Startup Doubler work as intended. Please send me a short e-mail if you have a problem thatÕs not described on the Startup Doubler web page and I'll try to fix it.
¥ Startup Doubler is not compatible with FWB TurboBoot.
¥ Startup Doubler is compatible with Speed Doubler 8.0 and 2.03.

Frequently Asked Questions
Q: How do I measure exactly how much time Startup Doubler saves?
A: Start the timer when you see the happy Mac icon appear in the center of the screen, then stop it as soon as the first disk icon appears in the Finder!
Q: Startup Doubler makes my system start up only 5 seconds faster. Why not more?
A: It really depends on the performance of your hard drive: the slower it is, the more dramatic Startup Doubler's result will be. For a very fast hard drive, however, the savings will be minimal.
Q: It's compatible with Speed Doubler 2.03, but what about Speed Doubler 8?
A: Startup Doubler is compatible with Speed Doubler 8! (versions 8.0 and 8.0b3)
Q: Is Startup Doubler similar to FWB TurboBoot?
A: No, and unfortunately they're incompatible. Startup Doubler should save much more time, though! On an un-networked PowerMac 7500/150 running System 7.6.1 off a Quantum Fireball 2gig hard drive, Startup Doubler cuts the startup time to 40 seconds down from 70 seconds!
Q: How is the acceleration achieved?
A: I guess you could say it adds a second level to the disk cache. I don't have a name for this technology yet :-) If you know some software that you think works the same way, please let me know!
Q: Do the savings from Startup Doubler and Speed Doubler add up?
A: Yes. Running either one alone will make your system faster: Startup Doubler accelerates the startup, and Speed Doubler's Faster Disk Performance accelerates most after startup. So running the two together is fastest!
Q: After installing Startup Doubler, TechTool reports that my System file is damaged. Is it?
A: No. TechTool is triggered by a small change the Startup Doubler installer makes to the System file.

Smart Scroll resizes the indicator thumb in regular scroll bars to show how much of a document is displayed in a window: If a window is displaying half of a document, the thumb will be half the scrollbar size. This gives you an idea of how large the document is, without having to scroll the window to find out!
Smart Scroll also adds Live Scrolling, which updates the display as you drag the scrollbar thumb. Just release the thumb when you see the part of the document you want: no more guessing where you'll end up! Get it from http://www.kagi.com/authors/marc/
