In order to circumvent the 500 MiB limitation of my current IDE drive, I would like to install a SCSI board in my ISA 486 box. As I was not a SCSI user at the time, I did some researches in the forum in order to determine how to set it up.
Now I would like to check that I understood well and I still have a few questions left opened.
I plan to buy an Adaptec 1542CP. It has an internal 50 pin connector and an external 50 pin “high density” connector. As I don’t plan to plug an external device, I will need to buy an external passive terminator.
At first, I will only plug internally a SCSI2SD v5 to act as a hard-drive. Later, I intend to buy a SCSI CD Writer. And here come the questions:
- I am right if I say that I need a cable sporting IDC50F connectors?
- Can I test the SCSI board without any device? Do I need an internal terminator in that case?
- Before I plug the CD Writer in, do I need a terminator in the unused connectors of my cable?
- The SCSI2SD documentation states that I can disable the terminator by removing some resistors. In which case would I want to do that?
- Do I need to plug the SCSI2SD at a specific location? The manual states:
Plug the last connector on the ribbon cable into the connector of the closest internal SCSI device.
Thus, it seems that the connectors are not “neutral”.
Plug the middle connector on the SCSI cable into the connector of the second internal SCSI device, if there is one.
The 1542CP is “Plug and Play” and provides a “BIOS”, thus the PC will recognize and boot on the SD card, but I will need EZ-SCSI when installing my CD.
- Do I need any other kind of software for DOS or Win3.11?
I understand that these questions may seem trivial for someone versed in the dark arts of SCSI, but I prefer to understand them before investing my money in the bards, cables and terminators.
Thus, if you have some answers or precisions for me, you’re very welcome! 😊
