This is ETHERS.SYS version 1.0 (1992)

This is a low-cost solution to share harddisk(s) among several PC
connected to ethernet wire. ETHERS.SYS is a DOS block driver.
It allow have read (NOT WRITE) access to remote disk. The network
interface is a packet driver. About 5K is required to install device.

USAGE:

1. Copy ETHERS.SYS to some directory, say c:\xxx.

2. Create file c:\xxx\ETHERS, the hostname to ethernet address
   database. The usual format is used, for example:
           # ethernet-address hostname
           02:60:8c:01:02:03 green
	   xx:xx:xx:xx:xx:xx hostname
   (To obtain addresses look to packet driver report).

3. Add device to config.sys. The syntax is:
     DEVICE=ETHERS.SYS [options] hostname:X[YZ...] green:c
     hostname - hostname from c:\xxx\ETHERS.
     XYZ  - remote block driver letter(s).
     options:
      /int=hex          packet driver interrupt (default - fisrt found)
      /type=hex 	ethernet type (default - 0xdfbc)
   If you omit mount request device work as server only.
   Don't use LOADHIGH (driver was written when no UMB) or be sure
   that 64K of UMB free at boot time.

4. Reboot PC.

5. Start packet driver.

6. Go to neighboring PC and repeat step 1-3.

7. Test ETHERS.SYS

For example, you want connect two PC, green on orange, add to
orange:ethers.	   <-	02:60:8c:01:02:03 green
orange:config.sys  <-	device=ETHERS.SYS green:c
green:config.sys   <-	device=ETHERS.SYS
Now on orange PC appear new drive.

NOTES:

- Device operate at block level, so read access only and recommendation
  to mount readonly disk. Also you can mount so-called block devices
  (harddisk,ramdrive,floppy,stacker,...) only.
- Device use ethernet type 0xdfbc, but some network software use
  this type, you can chage it.
- Device was tested for:
	3C501 
	AT286 & AT386 & ISA
	3.1 < MSDOS <= 5.0
- No security, so any host can read you files.
