(sic safely?)
You previously explained to me use of the extended
partition type C5h, instead of the old 05h type, to allow
DR-DOS 7.03 coexist with a LBA enabled OS using disk
space above 8 Gb.
Will you elaborate on the combination of the DR-DOS 7.05
IBMBIO.COM and DR-DOS 7.03 IBMBIO.COM files? I
understand one's need to ensure the hard drive doesn't
contain any FAT32 partitions. I agree that a binary patch
to keep the 7.05 BIOS from logging into FAT32 partitions
is a useful saftey net.
If I use a PC with a flash BIOS that supports LBA hard
drives, what does this 4th solution offer that the former
doesn't?
I assume it limits one to using a single OS on the hard
drive?
Since no FAT32 partitions are used (or read with the
binary patch) DR-DOS 7.03 is still limited to 2 Gb
partitions isn't it?
Would this combination of IBMBIO.COM files and the
binary patch mean the evolution of DR-DOS 7.03b to
DR-DOS 7.03c?
I for one would like to know more about this solution and
the binary patch also.
Thank you,
John =20
