#552 IBM AIX 1.3.0 Boot_Diskette1.img encounters unexpected errors
Tested with svn revision 4449 (Fri, 23 Apr 2021).
Steps to reproduce:
wget http://ps-2.kev009.com/aixps2/InstallImages/boot_esdi/Boot_Diskette1.img
dosbox .
boot boot_d~1.img
Actual:
IBM AIX 1.3.0 Boot disk prints these errors to the screen.
fd: error on media change test
FD error: drive=0, block=16, buf addr=69806197, fdtype = 18,errcode 0
SENSEFAIL
dlook: not a directory
isadevcfg.info not found
posinit: Errror opening isadevcfg.info
Press Enter to continue
dosbox prints the following:
15182622: FILES:file open command 0 file Z:\boot.COM
Loaded disk 0 from swaplist position 0 - "BOOT_D~1.IMG"
Loaded disk 1 from swaplist position 0 - "BOOT_D~1.IMG"
15182631: BIOS:Keyboard layout file auto not found
15182631: BIOS:Keyboard layout file auto not found
15384922: CPU:Illegal Unhandled Interrupt Called E
15385382: BIOS:INT13: Function 16 called on drive 0 (dos drive 0)
Expected:
The boot disk should load the IBM AIX boot menu without the above errors. The test image boots fine under the 86box emulator as a floppy image.
The BIOS function for the floppy change-line status is not emulated, likely because it is not needed by games. However, even if the function were sufficiently implemented, the software in question appears to rely on the NVRAM of the PS/2, and DOSBox does not emulate that system.
