Have you used many DOS emulators? Such as DOS BOX, VPC, VMWARE, etc. Except for dosbox, the other virtual hosts are powerful (of course, the volume is also large) and the requirements are also high.
In most cases where Windows 7 has been used today, do you know what an IBM PC 515 is? (Heating and dyeing, it's an antique)
Let's take a look

This is DOS 5.0 emulated under Windows 2000
PCE/ibmpc is an emulator of the IBM PC. It can emulate the hardware of most IBM PC 5159s, can boot DOS and run many DOS applications.
Simulation specifications:
CPU 8088, 8086, 80186, 80188. The specific CPU model can be set, and the default is
80186
MEM The basic memory of the original IBM PC is 640KB (yes, it's KB, that is, 0.6MB, not as much as one millionth of your hard disk)
BIOS The pure original version of the IBM PC or IBM PC/XT BIOS. This is copied from the host
8237 DMAC Supported, but not particularly useful
8250 UART Supported
8253 PIT Only supports counting modes 0, 2 and 3
8255 PPI Supported
8259 PPC Supported
Sound Sound is not supported for the time being
Display Supported video cards are: MDA, CGA, Plantronics ColorPlus,
Wyse 700, HGC, EGA, VGA
EMS Supported, with its own DOS driver
XMS Supported, with its own DOS driver
DISK Virtual 360KB floppy disk
Mouse Serial port Microsoft fully compatible mouse
Take a look at a few more screenshots

When the original IBM PC has no system disk to boot, the entered ROM BASIC

MSD in CGA text mode

VGA 16-color Windows 3.0

This is the predecessor of DOS, CP/M-86
