Unofficial (and unsupported) AIC78XX.MPD version table

Notes:

1. These versions are commonly recommended by the knowledgeable contributors to the Adaptec CDR users list as providing the best support with least problems when burning CDR. These opinion's are purely the opinion's of the contributors and in no way reflect any official or unofficial recommendation by Adaptec Inc.
2. This version of the 7800 Family Manager Set was released to OEM's only. It has never been released to distributors of Adaptec products.
3. Adaptec's .MPD drivers where never included in EZSCSI 'Lite' or 'L' versions. The .MPD drivers where only ever included on the Master Installation disk of the FULL version of EZSCSI.

What Changed?

V1.20 to V1.21

1. For Adaptec 7880 chips embedded on motherboards only the v1.21 driver now correctly negotiates the Sync. Transfer rate as set in the System BIOS.
2. V1.20 scanned PCI buses using hardware mechanisms 1 and 2 as outlined in the PCI specification. V1.21 uses INT1A to call the system BIOS and complete the scan. This change provides increased compatibility on systems with multiple bus architectures.

V1.21 to V1.22

1. Win95 displays 8 SCSI devices on Philips CDD2000/HP4020 device. Caused by the device returning a SCSI check to an Inquiry on LUNS 1-7. V1.22 corrects this error

V1.22 to v1.30

1. Added support for AHA2940AU (AIC7860 Ultra Narrow SCSI chip), AHA3940U Multichannel PCI-UltraSCSI Host Adapter, AHA3940UW Multichannel PCI-UltraSCSI Wide Host Adapter and AHA-3940UWD Multichannel PCI-UltraSCSI Wide Host Adapter with two external connectors.
2. Improved Windows 95 driver support for CD-ROM changers. Expanded to include newer or slower CD-ROM changers.
3. Fixed problem in the 78xx.inf file, previously the 78xx.inf file omitted a critical installation section. The omission affects host adapters which are not listed in the embedded Windows 95 SCSI.inf file. If the adapter being installed was not listed in the Windows 95 SCSI.inf file, the proper class would not be assigned and the miniport driver would not load correctly.
4. Fixed phantom LUN problem, where an inquiry issued to a Logical Unit that supports no device AND returns a check condition would cause multiple device to appear under Windows 95.
5. Increased scatter/gather segment count from 16 to 17.
6. Multichannel configuration information, fixed incorrect configuration information access for multichannel host adapters (eg. AHA-394x family). Previously, configuration information access for all channels defaulted to channel "A" settings. The driver now reads proper configuration information for each channel.

V1.30 to V2.xx

1. Add support for the AHA-2944UW
2. New Architecture, upgrade from the Hardware Interface Module (HIM) to the Common Hardware Interface Module (CHIM). The CHIM is designed for higher performance and greater forward compatibility with new I/O bus technologies.
3. The driver now possess the capability to gather statistics on I/O performance and to log I/O errors as they occur. Statistics or error log information is retrieved with appropriate Adaptec software or through programmatic interfaces.
4. Subsystem IDs supported in accordance with PC97 Phase 1 specification. PC97 compliance requires that both subsystem vendor IDs and subsystem device IDs be non-zero values
