// TMV1 Adapter Specific File

|

// See also cardtxxx.h, cardtxxx.h may redefine some functions with #defines.
|

//
|
|
// Revisions:
|
|
// 09-01-92 KJB First.
|
|
// 03-26-93 JAP Fixed up typedef and prototype inconsistencies
|
|
// 04-05-93 KJB Fixed definition problem for WINNT.
|
|
// Involving CardAddressRange...
|
|
// 04-22-93 JAP Added AdapterInterrupts[] and CardGetIRQ().
|
|
// 05-05-93 KJB Fixed CardSetInterruptLevel so that it calls
|
|
// MV101SetInterruptLevel like it should.
|
|
// 05-12-93 JAP Altered CardGetShortName() to return only
|
|
// the type of card.
|
|
// 05-13-93 KJB Added CardParseCommandString for card specific
|
|
// standard string parsing across platforms.
|
|
// Changed CardCheckAdapter to accept an
|
|
// Initialization info from command line, ie
|
|
// force bi-directional ports, etc.
|
|
// All functions that used to take an PBASE_REGISTER
|
|
// parameter now take PWORKSPACE. CardCheckAdapter
|
|
// takes the both the PBASE_REGISTER and the
|
|
// PWORKSPACE parameters. Auto Request Sense is
|
|
// now supported.
|
|
// 05-13-93 KJB Merged Microsoft Bug fixes to card detection.
|
|
// 05-14-93 KJB Removed P3CDoIo, it did not work for scatter gather.
|
|
// 05-17-93 KJB CardAddressRangeLength now return 0xffff.
|
|
// Fixed compiler warnings.
