DAYSTAR FAQ

• QUESTION: What version of Mac OS software should I be using? ANSWER: We recommend moving up only as your needs change. Often, the latest software introduces more problems than solutions. If you must upgrade then please note that DayStar is only contracted by Apple for upgrade support through Mac OS 7.5.1. Your warranty will not support any version higher than Mac OS 7.5.1

• QUESTION: I have a Turbo 040/Value 040 in my Mac II, IIx, IIcx or an SE/30 and now I am having problems after installing System 7.5. What do I do?
  ANSWER: Make sure you are using Mode32 version 7.5 for System 7.5 and QuadControl version 2.3 or higher.
  
  
• QUESTION: What do I do if I get a system error "Floating Point Coprocessor not installed" and then a system crash in System 7.x?
  ANSWER: Clearing (or zapping) the Parameter RAM will resolve this problem if you have a Floating Point Coprocessor. To clear the Parameter RAM press COMMAND- OPTION PR keys simultaneously during the complete startup sequence. Once you hear the second bong or startup sound release the pressed keys. Beware: If you clear the PRAM on non 32 Bit clean machines, it will default to 24 bit mode.

Some confusion has arisen concerning the Turbo 040 and Value 040's support of System 7.5. This TSB describes the possible problems a user may encounter and how these problems may be rectified.

• System 7.5 Compatibility Mac IIci, LC, LC II, Performa 400, 405, 410, and 430 – System 7.5 fully supported in 32-bit mode.
  • Solution: Customers wishing to use 24-bit mode should upgrade to QuadControl 2.3 or higher.
    
    
• Mac IIvi, IIvx, Performa 600 – System 7.5 not currently supported.
  • Solution: Use System 7.1.2 or under until the ROM update (version 4.1.1) is available in February 1995. Users should then also use QuadControl 2.3 or higher.
    
    
• Mac II, IIx, IIcx & SE/30 – System 7.5 supported in 32-bit mode, requires MODE32 7.5 & QuadControl 2.3.
  • Solution: QuadControl 2.3 and MODE32 7.5 must be installed when using the Turbo 040 with System 7.5. Versions of MODE32 prior to this release can corrupt System 7.5. Users who have already installed System 7.5 and have used a version of MODE32 other than MODE32 7.5, must reinstall System 7.5 and use only MODE32 7.5. (MODE32 7.5 is now included with the Turbo 040 software.) 24-Bit Mode: A System 7.5 bug prevents the Turbo from being able to run in 24-bit mode in these machines. Before installing the Turbo 040, be sure to install MODE32 and turn on 32-bit addressing in the Apple Memory Control Panel. Apple's System Update 4.0, due in January, will fix this problem. (Most users run in 32-bit mode and do not require 24-bit mode.) Note: Clearing (or zapping) the Parameter RAM will force the Mac into 24-bit mode. If this happens and the user is not using the System Update, they will need to remove the Turbo 040, turn 32-bit mode on and then reinstall the card.
    
    
• Apple Virtual Memory - Due to changes in System 7.5, users may not be able to run Apple's Virtual Memory with the Turbo or Value 040. (Connectix RAM Doubler is not affected and works fine.)
  • Solution: DayStar plans to provide a fix in ROM update version 4.1.1, scheduled for February 1995. QuadControl and ROM Update Availability QuadControl 2.3 will begin shipping 1/19/95. Existing customers may obtain the control panel via: DayStar Technical Support 404-967-2077, DayStar's BBS 404-967-2978, AppleLink, CompuServe, America Online, eWorld or GEnie. Customers that require the ROM update should contact DayStar technical support.
    
    
• Miscellaneous Compatibility Issues: FWB SCSI JackHammer Users may experience problems when using the FWB SCSI JackHammer NuBus card with the Turbo 040.
  • Solution: DayStar is working closely with FWB to fix this problem. It is currently believed that the problem resides with the SCSI JackHammer. Call DayStar for the latest information.
    
    
• Now Utilities 5.0 and QuicKeys 3.0 Users may experience problems when using these utilities with the Turbo or Value 040.
  • Solution: Update the Turbo or Value 040 ROM to version 4.01 or greater.
    
    
• OptiMem and Central Point Anti-Virus Users may experience problems when using these utilities with the Turbo or Value 040.
