   From: ohland@charter.net   
      
   Since there is no documentation for use with IBM SCSI, we don't have to   
   worry about following it :)   
      
   I assume this is the Bermuda? If so, max IML drive is 3.94GB.   
      
   Perhaps... the IBM SCSI controller wandts to see the Sector and Track info?   
      
   What SCSI HD do you wandt to emulate? I'm not sure if you need the   
   Vendor, Product, Version, and Serial, does the IBM system programs or   
   the SCSI BIOS even czech for that?   
      
   My SWAGs for ini:   
      
   [SCSI]   
   # Settings that apply to all devices   
   Debug = 0   # Same effect as DIPSW2, enables verbose log messages   
   SelectionDelay = 255   # Millisecond delay after selection, 255 =   
   automatic, 0 = no delay   
   PhyMode = 0   # 0: Best available  1: PIO  2: DMA_TIMER [?]   
      
   # Settings that can be needed for compatibility with some hosts   
   Quirks = 0   # 0: Standard, 1: Apple, 2: OMTI, 4: Xebec, 8: VMS   
   EnableUnitAttention = 0 # Post UNIT_ATTENTION status on power-on or SD   
   card hotplug [?]   
   EnableSCSI2 = 1 # Enable faster speeds of SCSI2 [?]   
   EnableSelLatch = 0 # For Philips P2000C and other devices that release   
   SEL signal before BSY [?]   
   MaxSyncSpeed = 5 # Set to 5 to enable synchronous SCSI mode   
      
      
   # Settings that can be specified either per-device or for all devices.   
   #Vendor = "QUANTUM"   
   #Product = "FIREBALL1"   
   #Version = "1.0"   
   #Serial = "0123456789ABCDEF"   
   #Type = 0     # 0: Fixed   
   #TypeModifier = 0  # Affects only INQUIRY response  [?]   
   #SectorsPerTrack = 63   
   #HeadsPerCylinder = 255   
   #RightAlignStrings = 0 # Right-align SCSI vendor / product strings,   
   defaults on if Quirks = 1 [?]   
   #PrefetchBytes = 8192 # Maximum number of bytes to prefetch after a read   
   request, 0 to disable   
   #ReinsertCDOnInquiry = 1 # Reinsert any ejected CD-ROM image on Inquiry   
   command   
      
   # Raw sector range from SD card can be passed through   
   # Format is RAW:first_sector:last_sector where sector numbers can be   
   decimal or hex.   
   # If end sector is beyond end of SD card, it will be adjusted automatically.   
   # [SCSI4]   
   # IMG0 = RAW:0x00000000:0xFFFFFFFF # Whole SD card
