;NO pc1440 disks supplied has a ID table in Sector 5 as is required by BIOS22I 
;   and specified in the help files
; 
; all BIOSes (CPM2.2/3.0/MPM for pc1440 disk images) 
; except BIOS22I, default to PC1440 disk images
; so ID tables were not needed.
;
;until i added BIOS22I, which requires ID tables for any pc1440 Disk Image placed in drives C or D
;
;This ID table is for PC1440 disks. IF you use drives C and D of BIOS22I for PC1440 
;disk images, you must add the ID table to the disk image, in sector 5; else without the ID table, 
;BIOS22I will default drives C and D to IBM3740 disk images
;
; if you add this ID table to a PC1440 image, then BIOS22I's Drives C and D will properly access it
;
;To add the Disk Definition (128 bytes) from a binary file to a PC1440 disk Image (sector 5) with DD.EXE..
;
;  dd.exe if=<IDT1440.bin> of=<DiskImageFile> bs=128 skip=4 count=1
;
;DO NOT ADD to non pc1440.img files. the Jade ID table is different and in sector 1, and is added with 
;the format program found on the jade disk images.
