Go for v3. Are both installs all floppy or CD. Can you provide more info about the system you are installing OS/2 on? Hdd size/type, amount of ram etc.
Thread needs to be moved to Marvin.
Both are using the floppy until the point it crashes.
The system is UniPCemu running a Compaq Deskpro 386 with 16MB RAM, ET4000 graphics(1MB VRAM), 2GB HDD with 386 windows 95-compatible XT-IDE BIOS as the second option ROM, Plop boot ROM as the third option ROM(ran with F8 on the XT-IDE BIOS) hooked and a floppy BIOS as the first option ROM(all starting after the ET4000 ROM at 2K aligned addresses).
The emulated FDC is a 82077AA, with two floppy drives each being a 1.44MB drive when unmounted(same with CMOS RAM byte 10h, set to type 4(1.44MB) for both drives). Only the first drive is mounted with OS/2.
No second HDD is mounted on the primary ATA-1 channel.
The secondary ATA-4(ATAPI) channel has 2 CD-ROM drives(ATAPI), with the master being the OS/2 warp 4 CD-ROM, the slave unmounted.
The motherboard has a rev J.4 ROM, with all hardware specified in the Compaq Deskpro 386 technical reference guide(same as AT, with memory bytes mapping at 80c00000h with it's functionality and second PIT with failsafe timer, no FPU and it's I/O ports emulated). All memory holes are fully emulated, all the way up to 4GB(each one shifting it's memory after it to the next area and precious hole's memory, so the 640K-1M to 1M+, 15.4-ROM/remap area(FA0000) before 16M with E0000-FFFFF redirection to after 16MB+(after the previous memory hole's remainder and 3GB-4GB being remapped to 4GB+ with the previous 2 area's remainder, which is currently inaccessable with the 32-bit CPUs(up to Pentium) emulated.
Also, this isn't marvin, as it's still an emulated system(UniPCemu).
