BlueSCSI does not boot Mac SE

Posted by: BobDaAggie on 2026-03-16 16:34:16

So I have finally purchased and installed an internal BlueSCSI for my Mac SE. The BlueSCSI does not boot the Mac. I can boot it off of my external BlueSCSI and when I do the drives that are set up in the internal BlueSCSI do show up.

I swapped the SD cards around but nothing I did could get the Mac SE to boot off the BlueSCSI. I enabled debugging mode and have attached the log.

Any help would be greatly apreciated.

Your log shows:

[4961ms] DBG Waiting for USB enumeration to enter Card Reader mode.
[6061ms] DBG Waiting for USB enumeration timed out after 1000ms.
[6061ms] DBG -- Try increasing 'USBMassStorageWaitPeriod' in the bluescsi.ini

Did you try what it suggested?

1000ms is not enough.

Okay, I thought that I had done that with the dwell time but I will check in my system file

Have you tried booting without an INI file? It's not really needed for normal operations for common machines like the SE.

So I increased the time to 10000 and then to 999999 but it did not work. I then deleted the ini file and it still did not work. This is my latest log file

The SD Card Formatter is probably worth trying. Like it says on the bluescsi.com site, use the overwrite format option to really go low level.

I saw that but because the external BlueSCSI works with the SC card I dismissed it.

I will try that and see what happends

Okay, thanks for the may suggestions. I have attempted all of them. In my latest log I have found this line:

[14312ms] DBG ---- STATUS: 2 CHECK_CONDITION, sense code 0x05, asc 0x00002000
[14318ms] DBG ---- MESSAGE_IN

in my searching I have found this github thread:

It states that Data Line 2 is stuck and I probally need a new Pico.

I will do more testing but I think that I am getting closer
