The author respectfully requests that any modifications to this software be |

sent directly to him for evaluation and testing. |
|
|
|
Special thanks to Wayne Yen, Jin-Lon Hon, and Alex Win of BusLogic, whose |
|
advice has been invaluable, to David Gentzel, for writing the original Linux |
|
BusLogic driver, and to Paul Gortmaker, for being such a dedicated test site. |
|
|
|
Finally, special thanks to Mylex/BusLogic for making the FlashPoint SCCB |
|
Manager available as freely redistributable source code. |

CCBs only in having the TagEnable and QueueTag fields moved from byte 17 to |

Extended LUN Format CCBs can support up to 64 Logical Units, but in practice |

the SCSI-2 specification defines Bit 5 as LUNTAR. Extended LUN Format CCBs |

are used by recent versions of the MultiMaster Firmware, as well as by the |

FlashPoint SCCB Manager; the FlashPoint SCCB Manager only supports 32 Logical |
|
Units. Since 64 Logical Units are unlikely to be needed in practice, and |

since they are problematic for the above reasons, and since limiting them to |

5 bits simplifies the CCB structure definition, this driver only supports |

32 Logical Units per Target Device. |
