Welcome to the x86 hell. >=20 > error 1 is: Invalid command. And it is resulting firstly from = drvsize() (the lone =E2=80=9Cerror 1=E2=80=9D messages) and then from = drvread(). Now the question is, did you do the install from usb stick or = cd, and has this system booted fbsd from the disk before? >=20 > The question is up because, the boot2 is only using INT13 extended = read (INT13 EAX=3D0x4200) and INT13 EAX=3D0x4800 to get disk size; if = the read is now getting error but was working before, it is pointing = towards the error from 0x4800 (drvsize) is triggering the error with = read - meaning we should probably attempt the disk reset on error. >=20 > As an first take on possible fix, I think we need to address the = drvsize() to get size from INT13 0x800 as biosdisk.c bd_int13probe() = does, and reset the disk on error.
