Anyone got documentation on Zulu SCSI v1.1 2022 card?
Preformatted the SD card with FAT just to be sure it was good.
Adapter does not detected in Windows 10 usb
What settings should the switches on top be set to for the adapter to work just a simple HD in a 9577.

Windows 10 and USB. Uh, I'm not sehr klar, but isn't that USB port [DFU]
for bootloading? That is, it is not for normal operation?
FAT? Might work, who knows, but FAT32 might be better for Win 10, no
idea on the drive size.
Configuration - Configure using FAT32 or exFAT-formatted SD or microSD card.
What settings should the switches on top be set to for the adapter to
work just a simple HD in a 9577.
For ZuluSCSI V1.1, the DIP switch settings are as follows:
ON or OFF DEBUG: Enable verbose debug log (saved to zululog.txt)
ON if last device on chain TERM: Enable SCSI termination
OFF BOOT: Enable built-in USB bootloader, this DIP switch MUST remain
off during normal operation.
OFF SW1: Enables/disables Macintosh/Apple specific mode-pages and
device strings, which eases disk initialization when performing fresh
installs on legacy Macintosh computers.
I did look at ZULU SCSI, and sent a few messages to the developer,
regarding use with Micro Channel. It looks like you are the pioneer.
What O/S are you using?
What size of an SD do you have?
I'm not sure if you have a suitable HD image on the SD card. Honestly, I
feel I was the one editing the ZULU SCSI page, it's Kaotic, but without

ZuluSCSI can be configured in more detail via an optional text file
named zuluscsi.ini

SD card requirements
The ZuluSCSI firmware requires a MBR/DOS-partitioned SD card, and at
least one FAT32 or exFAT-formatted SD partition, which must be labeled
SDHC or SDXC. Older SD cards manufactured prior to around 2008,
generally ~4GB and smaller, may not be detected by the SDIO interface of
the microcontroller. This is a hardware/silicon limitation. ZuluSCSI has
no upper limit on the size of SD cards it is compatible with, and is
known to work with large 256GB and 400GB SD cards which are currently
commercially available. SD cards partitioned with GPT (GUID Partition
Map) can not be read by ZuluSCSI, and the ZuluSCSI will not detect such
SD cards, resulting in the LED flashing five times.

single, valid disk image file
What is this? I grok the idea, but just saving 1GB of empty space [ex.
0662] isn't klar to me.

I use Acronis True Image and the image it creates is about the size of
the used space in the partition you are backing up and you can lay
that back down on a smaller drive/partition if it fits. It doesn't
back up empty space.

Not looking good. Basics failing.
Using a iBM Model 77 (9577)
-2GB Kodak SD card format to FAT32
-Windows95 boot disk img named as HD6.img copied to the card where the 6 is suppose to be the SCSI ID.
-put into the end position of the SCSI cable, termination sw on with power cable plugged in..
Machine errors as no boot device was found...

I am not klar on the disk image source.
W95 boot disk img.
What image? Of a CD? An image of a real W95 boot drive, spinning
platters to an image file?

So it turns out you don't load real img to the drive. Just a dummy file of size X with the extension of img and that becomes like the "drive raw space" I guess to be later OS operated on..
Still working with support because the model 77 doesn't like the SCSI side of things. Might be an ini work around.

Since there is no documentation for use with IBM SCSI, we don't have to
worry about following it :)
I assume this is the Bermuda? If so, max IML drive is 3.94GB.
Perhaps... the IBM SCSI controller wandts to see the Sector and Track info?
What SCSI HD do you wandt to emulate? I'm not sure if you need the
Vendor, Product, Version, and Serial, does the IBM system programs or
the SCSI BIOS even czech for that?
My SWAGs for ini:

Debug = 0 # Same effect as DIPSW2, enables verbose log messages

Quirks = 0 # 0: Standard, 1: Apple, 2: OMTI, 4: Xebec, 8: VMS
EnableUnitAttention = 0 # Post UNIT_ATTENTION status on power-on or SD
card hotplug [?]
EnableSCSI2 = 1 # Enable faster speeds of SCSI2 [?]
EnableSelLatch = 0 # For Philips P2000C and other devices that release
SEL signal before BSY [?]

EFIC (Empty File Creator) is a small and reliable application that
create empty files in various sizes.
Is this needed to create the HD "image" ?
