$VER: pcmciacd.device 1.2 (23.01.2023)

About

-----

PCMCIACD.devie is a device driver for the Sony PCGA-CD51/A PCMCIA CD-ROM.

These drives do not require any additional power to operate and plug

directly into the PCMCIA port.

Reported working drives

- Sony CRX75A (16bit switch enabled)

- Sony PCGA-DVD51 (reported by user, not personally tested)

The device driver supports hot plugging of the CD drive during operation.

Removal of the card will appear as a normal CD ejection.

The pcmciacd.device will work alongside other device drivers such as

compact flash and network cards.

Support

-------

This driver has been developed primarily for the A1200 and works with

AllegroCDFS, CDFileSystem, CacheCDFS, AmiCDFS and AsimCDFS.

Execution has been successful on WB 3.1, 3.14 and 3.2.

Some limited testing has also been run on a base A600 68000 using AmiCDFS

on WB 3.1.

Card reset patch is recommended for correct operation due to a bug in the

PCMCIA implementation. Without this utility the card could fail to detect

properly if the driver is expunged from memory and then reinitialised.

This is an edge case for general use so not essential.

A work around solution is to eject the card and reinsert to perform a hard

reset if the drive stops working without CardReset patch.

See Aminet: util/boot/CardReset.lha

WB 2.0 is untested, but may work as the code uses only V36 library calls.

I cannot support any issues with the underlying file system used, which

may have their own bugs or limitations. Please read the documentation that

came with the file system to determine supported features and configuration.

Misc Notes

--------------

Streaming videos from AmiCDFS using AGABlaster 0.9.91 has issues with the

playback. Remove all Control options from the mount file with:

Control = ""

PlayCD distributed with 3.9 checks the supported standards flags when

querying the CD-Drive. Sony ATAPI drives do not report full standard

support, but the driver fakes SCSI-2 anyway to allow the player to work.

Note that PlayCD still has some issues when playing back.

I prefer PlayCDDA from Aminet mus/play/playcdda_gui.m68k-aos.lha because

this plays through the Amiga without mixing audio.

Driver Install

--------------

Copy pcmciacd.device to DEVS:

A mount file will need to be setup in DEVS:DOSDrivers. You can use the

example mount file included in the archive that requires AmiCDFS or update

an existing mount file by updating the tooltips and change to:

DEVICE=pcmciacd.device

UNIT=0

Only unit 0 exists for this driver on the PCMCIA card bus.

See Aminet: disk/cdrom/amicdfs240.lha

A newer version than 40.11 of the CDFileSystem is needed to run on

WB3.1. If this isn't available then AmiCDFS works for 3.1 and potentially

older versions of Workbench

Versions

---------

1.2 - 23rd Jan 2023: Improved detection of ATAPI devices, especially for

constant powered drives such as CRX75A.

1.1 - 18th Jan 2023: Fix for divide by zero issue on fast Amigas running

PiStorm.

Slight increase of read speed from version 1.0

1.0 - 30th Dec 2022: First release. Tested on 68000 A600, 030/060 A1200

IMPORTANT NOTE:

---------------

Testing has been conducted with various devices, but there

may be unforseen issues with other PCMCIA cards causing crashes or

even damage to some types of card or data associated. Whilst this

risk should be very low the driver needs to prod and poke devices

to determine their function and not all types of PCMCIA cards will

react to probing in the same way.
