The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting the bug state to "Incomplete" now.
If the bug has already been fixed in the latest upstream version of QEMU,
then please close this ticket as "Fix released".
If it is not fixed yet and you think that this bug report here is still
valid, then you have two options:
1) If you already have an account on gitlab.com, please open a new ticket
for this problem in our new tracker here:
https://gitlab.com/qemu-project/qemu/-/issues
and then close this ticket here on Launchpad (or let it expire auto-
matically after 60 days). Please mention the URL of this bug ticket on
Launchpad in the new ticket on GitLab.
2) If you don't have an account on gitlab.com and don't intend to get
one, but still would like to keep this ticket opened, then please switch
the state back to "New" or "Confirmed" within the next 60 days (other-
wise it will get closed as "Expired"). We will then eventually migrate
the ticket automatically to the new system (but you won't be the reporter
of the bug in the new system and thus you won't get notified on changes
anymore).
Thank you and sorry for the inconvenience.

Title:
ESP SCSI adapter not working with DOS ASPI drivers
Status in QEMU:
Incomplete
Bug description:
I have been trying to install the DOS ASPI drivers for the ESP scsi
card. Both in am53c974 and dc390 modes. Neither works but they don't
work in different ways.
The following things appear to be problematic:
* The am53c974 should work with the PcSCSI drivers (AMSIDA.SYS) but the ASPI
driver never manages to get past initializing the card. The VM never continues.
* The dc390 ASPI driver fares a little better. The ASPI driver loads and is
semi-functional but the drivers for the peripherals don't work.
- ASPI.SYS (creative name) loads
- TRMDISK.SYS fails to load when a cd-drive is attached and will crashs
scanning the scsi-id where the cd drive is attached
- TRMDISK.SYS loads without a CD drive attached but fails to read any
scsi-hd devices attached. The TFDISK.EXE formatter crashes.
- TRMCD.SYS loads, but can not detect any CD drives.
The various permutations:
am53c974 hang on ASPI driver load: (CD only attached)
~/src/qemu/build/qemu-system-i386 -m 64 -device am53c974,id=scsi0
-device scsi-cd,drive=drive0,bus=scsi0.0,channel=0,scsi-id=0,lun=0
-drive file=../Windows\ 98\ Second\ Edition.iso,if=none,id=drive0 -vga
cirrus -fda am53c974_aspi.img -bios /home/hp/src/seabios/out/bios.bin
-boot a -trace 'scsi*' -trace 'esp*' -D log
dc390 crash because of CDROM attachment and loading TRMDISK.SYS (Only CD
attached)
~/src/qemu/build/qemu-system-i386 -m 64 -device dc390,id=scsi0,rombar=0
-device scsi-cd,drive=drive0,bus=scsi0.0,channel=0,scsi-id=0,lun=0 -drive

dc390_all.img -bios /home/hp/src/seabios/out/bios.bin -boot a -trace 'scsi*'
-trace 'esp*' -D log
dc390 successful boot, but TRMDISK.SYS not working (TFDISK.EXE will crash)
~/src/qemu/build/qemu-system-i386 -m 64 -device dc390,id=scsi0 -device
scsi-hd,drive=drive0,bus=scsi0.0,channel=0,scsi-id=0,lun=0,logical_block_size=512

/home/hp/src/seabios/out/bios.bin -boot a -trace 'scsi*' -trace 'esp*' -D log
dc390 successful boot, TRMDISK.SYS not loaded, only TRMCD.SYS. CDROM not
detected
~/src/qemu/build/qemu-system-i386 -m 64 -device dc390,id=scsi0,rombar=0
-device scsi-cd,drive=drive0,bus=scsi0.0,channel=0,scsi-id=0,lun=0 -drive
file=../Windows\ 98\ Second\ Edition.iso,if=none,id=drive0 -vga cirrus -fda
dc390_cd.img -bios /home/hp/src/seabios/out/bios.bin -boot a -trace 'scsi*'
-trace 'esp*' -D log
All of these tests were done on
7b9a3c9f94bcac23c534bc9f42a9e914b433b299 as well as the 'esp-next'
branch found here: https://github.com/mcayland/qemu/tree/esp-next
The bios file is a seabios master with all int13 support disabled.
With it enabled even less works but I figured this would be a seabios
bug and not a qemu one.
The actual iso and qcow2 files used don't appear the matter. the
'small.qcow2' is an empty drive of 100MB. I have also tried other ISOs
in the CD drives, or even not put any cd in the drives with the same
results.
I will attach all of the above images.
