The following is a Forensic Examination of the IBM PC DOS 1.00 diskette, and according to the MD5 sum you'll find there, this file is an identical match to the original:

There are other pages describing its physical diskette as well.

Using DEBUG to write the disk is certainly more interesting, and I confirm that following those instructions produces a bootable diskette that looks and acts just like the original. However I found another download here on vetusware.com that has the same image file (date/time stamp off by an hour) and includes a program DCOPY.EXE that writes the disk. DISKCOMP on the two finds
Compare error(s) on track 08
Compare error(s) on track 09
so perhaps the DEBUG instructions are close but not perfect for reproducing the diskette exactly.
The other file (with DISKCOPY included) is listed under
PC-DOS 1.00

RENAME.
To write the image-file to a disk load it with DEBUG and e90a1 bb 00 01
ba 00 00(or ba 01 00 for drive B:)b9 01 00 b8 08 03 cd 13 72 0b
81 c3 00 10 fe c5 80 fd 09 75 ee cd 20. Then g=90a1 90bc. If you won't
read CX=0000, g=90aa 90bc, or try m 100 90a0 5000:100, res 5000
and g=90aa 90bc.
To run the BASIC programmes, use #5871 PCBASIC.RAR (select IBM/MSDOS below).

I confirm that's a copy of the original disk. You may search with an hexeditor for some strings left in the unused space of the sectors, as "Boca-Raton".
Tested also on DosBox under Linux, beside real hardware.
