There are new features in the AHA-1540C/1542C that are not backwards compatible with the AHA-1540B/1542B. For example, on the AHA-1540C/1542C, you could have disk drives at SCSI ID #0 and SCSI ID #4 and choose to boot from SCSI ID #4. The AHA-1540B/1542B can only boot from SCSI ID #0. Problems can arise if you load an older device driver that assume we boot from SCSI ID #0. Many software packages already support all features of the AHA-1540C/1542C, including Adaptec EZ-SCSI v1.0 and later, OS/2 2.1, etc. If you enable an AHA-1540C/1542C feature (e.g. dynamic scan) that may not be compatible with AHA-1540B/1542B software, and you use older software, the host adapter will suspend operation to protect you from data loss. There are some situations where a new AHA-1540C/1542C feature will still work with older drivers. For example, you can enable "dynamic scan" on the AHA-1540C/1542C with NetWare 386, and the older drivers are not affected by this. But since the older NetWare 386 disk drivers were written before the AHA-1540C/1542C came out, the host adapter will suspend operation. This is where ULK1540C.SYS may come in handy. ULK1540C.SYS is a DOS device driver that you load anywhere in your CONFIG.SYS. It simply unlocks the host adapter mailbox to force the host adapter not to suspend operation when older device drivers are detected. It takes up NO memory! There are two command line switches: /P{port} If you do not use this command line switch, the host adapter will default to port 330h. If your AHA-1540C/1542C is set for a different port address, you must use this command line switch. For example: device=c:\scsi\ulk1540c.sys /p334 /PAUSE This option makes your system pause after UKL1540C.SYS runs at boot-time so you can read the message that appears on the screen. If ULK1540C.SYS was unable to unlock the mailbox, one of the following error messages may appear: -> Invalid entry for '/p' setting Only port addresses 330, 334, 230, 234, 130, 134 are supported. -> Unable to initialize host adapter mailboxes -> Unable to read configuration from host adapter Make sure there are no hardware conflicts within your PC, the host adapter is properly configured, and that the host adapter is securely inserted. Check SCSI bus termination, SCSI parity, and cabling. -> An AHA-1540C/1542C is NOT present at port xxx There is no AHA-1540C/1542C at the give port address. Make sure there are no hardware conflicts within your PC, the host adapter is properly configured, and that the host adapter is securely inserted. WARNING: Using older drivers that do not know how to properly handle the advanced features of the AHA-1540C/1542C could lead to data loss or corruption. Use this utility with caution. ***************************************************************************** * %%% !ADP4C00.CFG %%% * ***************************************************************************** !ADP4C00.CFG is the EISA configuration overlay for the AHA-1540C/1542C and the AHA-1540CF/1542CF. ***************************************************************************** * %%% !ADP0100.CFG %%% * ***************************************************************************** !ADP0100.CFG is the EISA configuration overlay for the AHA-1540B/1542B. ***************************************************************************** * %%% VHDFMT.EXE %%% * ***************************************************************************** VHDFMT.EXE is the floptical format utility for the AHA-1540CF/1542CF. This utility allows for the formatting of 21 MByte floptical Very High Density (VHD) media. It is not intended for use with 1.44 MByte and 720 KByte media. The DOS format.com program is available for those media types. The VHDFMT.EXE utility creates a new root directory and File Allocation Table (FAT) for the diskette. It must have access to the DOS format.com utility through the DOS path command or the default directory where VHDFMT.EXE is invoked. ***************************************************************************** * %%% VHDCOPY.EXE %%% * ***************************************************************************** VHDCOPY.EXE is the floptical copy utility for the AHA-1540CF/1542CF. This utility copies the contents of the VHD diskette in the source drive to a formatted (low-level) VHD diskette in the destination drive and replaces the DOS diskcopy utility for this purpose. This utility works on VHD diskettes only. To copy 1.44 MByte and 720 KByte floppies on floptical drives, use the standard DOS diskcopy utility. ***************************************************************************** * %%% VHDCOMP.EXE %%% * ***************************************************************************** VHDCOMP.EXE is the floptical compare utility for the AHA-1540CF/1542CF. This utility compares the contents of two VHD diskettes and replaces the DOS diskcomp utility for this purpose. This utility works on VHD diskettes only. To compare 1.44 MByte and 720 KByte floppies on floptical drives, use the standard DOS diskcomp utility. ***************************************************************************** * %%% VHDMODE.EXE %%% * ***************************************************************************** VHDMODE.EXE is the floptical mode utility for the AHA-1540CF/1542CF. This utility sets DOS internal drive parameters of a floptical drive for standard (1.44 MByte) or VHD (21 MByte) parameters. This utility allows certain ill- behaved applications to run using VHD parameters. Applications that do not read a diskette's BIOS Parameter Block (BPB) from the disk's boot sector will generally fail on VHD media. An example of such an application is the Norton Disk Doctor(R), Version 6.0. It only runs whenever the drive default parameters are set for VHD media. It is recommended that the VHD internal parameters be reset back to standard after running applications that require VHD parameters. There is no assurance that vhdmode.exe will allow all ill-behaved app- lications to run. Some applications go directly to the ROM BIOS to obtain a drive's parameters instead of using DOS INT 21h services. These app- lications will fail even after running VHDMODE.EXE
