CSMWrap hangs on Surface Pro 1

[2W10]

Hi,

I am trying to make this work on my Surface Pro 1. But when I put it on the UEFI partition, it boots but hangs at SeaBIOS. I tried pressing ESC and 1-2 but nothing worked. How do I fix this?

I am using v1.2

FYI: I have gotten XP x64 Vista and 7 to work on the SP1: https://youtube.com/playlist?list=PLJgjiVZvN6T3lndRPzHltu8NiNwSkvweA&si=Hg6zf7cPkjgPOYtZ

Will look into it once I get some time.

K sounds good. I also got similar issues on my gaming PC

It's an intel 12th gen I think ![Uploading 446827000...]![Uploading 446827002...]![Uploading 446827003...]

It's likely to be another issue tho....

Why this UEFI firmware is having that much non-continuous memory maps that is even overflowing 128 e820 entries....

Ok so on my surface pro it started randomly working with freedos but it didn't load

Then I replaced it with windows 7 x86 and made it the active partition and now it's hanging at this screen again

It actually sounds like a issue on SeaBIOS disk driver.

Where was your FreeDOS/Windows7 image placed? SSD? USB flash disk? If it's USB was it USB 3.0?

Thanks

ok so it started to randomly work
it was on my ssd

my setup was
MBR disk
100MB partition with the csmwrap.efi placed in /EFI/BOOT and named as bootx64.efi

and then the Windows 7 x86/FreeDOS partition

I suspect this is a variant of previous AHCI issue, can you try this build: https://github.com/FlyGoat/csmwrap/actions/runs/15207637444

Thanks

i tried it it still isnt working

[2W10]

update: i tried installing ms-dos on there

it still hung but after a few reboots it actually said "press esc for boot menu"

It freezes on this screen tho
Think the driver might be buggy

[2W10]

also i dont think keyboard works either
btw i installed dos 7.10 on there

i think there may be some issues when u use ntfs partition idk

[FlyGoat]

SeaBIOS won't look into NTFS partition at all, it only reads MBR. Likely to be a hardware driver issue...

[2W10]

oh alr
u think it will be fixed soon?

To be honest I have no idea on the root cause. Will try to make a couple of improvements but can't promise on this problem.
