Macintosh Plus & SCSI2SD won't boot

[Tootai]

I got a SCSI2SD, but it refuses to boot without a floppy disk. If I boot from floppy, I can see the contents of the HD, but nothing much really runs because it's an older version boot disk.

I have tried all the USB power cords and adapters I have without success. The SD card shows up as scsi ID 1. It straight up refused to work with the 8GB image I had, but the 2 GB seems to work.

Any suggestions?

Fitting a SCSI2SD in a 68k Mac

Wow! I never figured this one out! I’m gonna try this with my Plus!

Here are some news for SCSI2SD and Mac Plus:

I used the description of MOS8_030. The vendor etc. were Seagate and ST225N. Device Size: 8 GB; HD SC Setup formated 20 MB. OS 6.0.8

Then I was able to format the 8 GB SD with Lido 7.56. I installed 4 Partitions (First 1 GB; 2-4: 2GB). Formatting and partitioning was done in Lido. Now I have 4 drives mounted and the plus booted from the first partition. For me Lido worked and produced a bootable SCSI2SD. When I tried this some weeks ago, it did not work. My SCSI2SD has firmware 4.8 (former was 4.7) and I use the newest software. I think the settings in the general settings tab are very important for creating bootable SCSI2SD for a Mac plus.

The description of MOS8_030 is on Page 3 in the Thread!

You definitivly need a seperate power supply for the SCSI2SD because the plus has no termination power. You can change this by installing a resistor on the LB.
