Which Apple SCSI card is it? The original card has a row of eight jumpers at the keyboard end of the card, and uses a rectangular 40-pin DIP version of the SCSI controller chip (NCR5380, if I remember the number right). The high-speed card has four DIP switches near the middle of the card, and has two sockets 44-pin square chips, one of which is the NCR53C80 SCSI controller. If you have the original Apple SCSI card, does it have the revision C firmware? This can be identified by the label on the ROM, assuming it is the original ROM from Apple. The revision C firmware is 341-0437-A. If the ROM label reads 341-0112A or 341-0112B, then you have older firmware and you need to upgrade to revision C in order to use the card with GS/OS. The high-speed SCSI card works with GS/OS, but you must be running System 5.0.4 or later, or use the drivers which were supplied with the card if you have System 5.0.3 or earlier. (I don't recall whether these drivers work with System 4.0, but I know they work with 5.0 and 5.0.2.) 3. Check the SCSI ID settings. The card should be set to SCSI ID 7 and the drive to anything other than 7 (the best choice is usually to set the drive to ID 6, which will minimise the delay at startup). Assuming all of that is correct, the next problem is that you need the SCSI drivers on your boot disk. This may be a little tricky if you are booting from floppy, because there might not be enough space. There are two files required in the */System/Drivers directory in order to support a hard drive on the Apple SCSI cards: SCSI.MANAGER and SCSIHD.DRIVER. You can use the System 6.0.1 installer's "Customize" option to install them on your startup disk, or copy them from the Install disk. Assuming that you want to set up the system to boot from the hard drive, I suggest the following procedure. 1. Boot from the System 6.0.1 Install disk. 2. Quit from the Installer. This will take you to the GS/OS launcher. 3. Insert the SystemTools1 disk, and launch the Adv.Disk.Util program. (If you only have one 3.5" drive, you will probably have to swap disks a few times.) If ADU can't see the hard drive, then there is a hardware or setup problem somewhere. 4. Locate your hard drive and partition it as appropriate. The main requirement is that the first partition must be ProDOS and cannot exceed 32 MB. If you have a particularly large hard drive, you may need to create lots of 32 MB partitions and/or one or more larger partition for use with HFS. 5. Quit from Advanced Disk Utility, insert the Install disk again, and launch the Installer. 6. Click on the Customize button. 7. Select the "*System 6:On HD or FDHD" item, and make sure the first partition of the hard drive is selected as the destination. 8. Install. 9. If necessary, go into the Control Panel and change the startup slot to the one containing the SCSI card. 10. Quit from the Installer, close the Launcher window, and choose the Shut Down command (in the File menu). 11. When you get the "it is safe to shut down" dialog, click on the restart button. You should now be booting from the hard drive, with a reasonably complete system. You can launch the installer to add additional items and/or copy files from elsewhere. > Have I to download an universal scsi hd driver to use it? The IIgs uses a generic driver supplied with the system software which supports all standard hard drives. It is a normal file, and is loaded part way through the boot process. The SCSI card firmware is responsible for accessing the drive up to that point (and for all hard drive access while running ProDOS-8 or other 8-bit operating systems, or the earlier 16-bit operating system ProDOS-16). There is no need for a special driver to be installed in its own partition, unless you want to use the hard drive on a Mac as well.
