Announcing ZuluSCSI - A file-based SCSI device emulator

@tcole This is very much not a dumb question :)

The default behavior of Classic Mac OS is to eject all optical drives at power-off. It seems it's not cycling to the second ISO, so it would be helpful if you could send us your zululog.txt, as well as a directory listing/screenshot of the ISO files you have on the SD card, so we can attempt to replicate the behavior.

Thanks! Heading out of town for the holidays, so I’ll send this when I’m back home late next week.

Attached is my zululog.txt and my zuluscsi.ini (I added .txt extension so the forums would let me upload it, I know you didn't ask for the .ini file, but through it might be helpful).

Here is a screenshot of the directory listing from the SD card.

It does cycle properly when I do a cold boot, then drag the mounted ISO to the trash. I can cycle through all 3 images just fine.

But when I do a reboot (Special -> Restart) the system doesn't have any of the ISOs mounted once it boots again. I have to do Special - Shut Down to get any ISO to mount again.

I also went ahead and upgraded to firmware 1.2.0, no change.

Hi all, trying to get my Mini 1.0 working with my MacPlus.

It simply doesn't see the disk to start from. I've attached the log; nothing looks out of place to me. The led blinks once and then goes solid.

I've tried 6.0.8 and 7.1 pre-made images (from the same source). My Classic II boots off the 7.1 images without a hitch; it's not capable of booting 6.0.8, but it reads the file system just fine.

I played with the config a bit, setting it to SCSI I (which, from what I understand, is what the Plus supports) didn't help.

Oh, and the Plus has the diode hack.

Thanks,

K

On your ZuluSCSI SD card, create a zuluscsi.ini file, and inside it, put the following two lines:

[SCSI]
Debug=1

Then, re-attempt booting, and send the contents of your zululog.txt to support@zuluscsi.com, where we can continue this conversation.

This thread is not intended for general technical support, but let's keep the conversation going via e-mail.

My apologies, I saw a few other tech questions, so I figured it was OK.

I'll send you my log in a bit.

Thanks,

Need some help. Trying to figure out two issues I am having while trying to use the ZuluSCSI 1.1 and ZuluSCSI Mini with my Quadra 700.

Issue #1: Use ZuluSCSI 1.1 (internal) and ZuluSCSI Mini (external) at the same time

I have the ZuluSCSI 1.1 as my only internal SCSI device and the ZuluSCSI Mini as my only external SCSI device. The ZuluSCSI 1.1 has termination enabled and the ZuluSCSI Mini doesn’t give you an option (it’s permanently enabled). Note that both units have the latest firmware installed.

I have a bootable image (7.5.5) on both of my SD cards. On one, I have named the image HD1.img and on the second, I have named the image HD5.img. Both the ZuluSCSI 1.1 and ZuluSCSI Mini are connected to my Quadra 700. If I only plug an SD card into my ZuluSCSI 1.1, my Mac boots fine. If I only plug an SD card into my ZuluSCSI Mini, my Mac boots fine. If I have both of my SD cards plugged into the Zulus, my Mac will not boot and gives me a question mark disk icon. Doesn’t matter if I swap SD cards. If I only use one SD card, it boots. If I use both, it does not. I have looked at the log files and both units show that the image is detected properly and no issues. There are no error logs. Enabling Debug = 1 doesn’t seem to give me any additional messages.

Can you only use one Zulu device at a time? I was hoping to have the internal one as my main boot device. And also use an external one to transfer files between Macs.

Issue #2: Using only the ZuluSCSI 1.1, can’t seem to have more than 2 disks on the SD card.

In this scenario, I am only using the ZuluSCSI 1.1 internally. The SD card has three images on it: HD1.img (bootable 7.5.5), CD4.iso (bootable CD which is an Apple recovery disk), HD5.img (blank 2GB disk image). The Quadra 700 refuses to boot (question mark disk icon). If I delete either the CD4.iso or the HD5.img, then the Quadra 700 boots fine. So I can boot with HD1.img and HD5.img, or I can boot with HD1.img and CD4.iso, but I can’t boot if I have all three images on the SD card. Again, the log file shows all three images are detected fine. There is no error log. And enabling Debug = 1 doesn’t seem to provide any additional messages in the log file.

I thought I read you can have multiple images on the SD card and have it work with ZuluSCSI 1.1. I must be doing something wrong?

Any help greatly appreciated, thanks!

BTW, I am also seeing the issue that tcole mentioned a few posts up where on a Restart, my isos fail to mount. I have to Shutdown first for the iso image to mount again.
