; Title: RTL8019 Plug-And-Play Packet Driver
;
; History: V1.00 -- 1994.07.29
; V1.10 -- 1994.09.05
; V1.20 -- 1994.10.05
; V1.30 -- 1995.07.05
;
; Notes: All changed codes are marked with the release date 'DD/MM/YY'.
; In other words, you may search '07/12/90' if you want to find
; the changed codes of a source program released on 1990.07.12,

;
; Name: PNPPD.100
;
; Version: V1.00
;
; Released By: tflin
;
; Release Date: 1994.07.29
;
; Changed File:
;
; Reason: New release version.
;
; Comment: When 2 or more 8019 cards are installed. This program will use
; the one which has lower PnP serial Number.

;
;
; Name: PNPPD.110
;
; Version: V1.10
;
; Released By: tflin
;
; Release Date: 1994.09.05
;
; Changed File: EXE/PNPPD.COM
; SOURCE/PNPPD.ASM
; SOURCE/TAIL.ASM
;
; Reason: 1. Driver supports at most 4 RTL8019 Cards.
;
; 2. Fixed the bug when in PnP environments, Jumper/Jumpless Card
; will not be found.
;
; 3. In multiple-card case, driver will print out all cards'
; information and prompt user to select one.
;
; Comment: 1. After the driver runs, CSN values of PnP Cards will be
; preserved. For Jumper/Jumpless cards, CSNs are set back to 0.

;
; Name: PNPPD.120
;
; Version: V1.20
;
; Released By: Jasper
;
; Release Date: 1994.10.05
;
; Changed File: EXE/PNPPD.COM
; SOURCE/PNPPD.ASM
;
; Reason: 1. Driver supports up to 8 RTL8019 Cards.
;
; 2. Uses direct IO scanning method to locate 8019 cards.

;
; Name: PNPPD.130
;
; Version: V1.30
;
; Released By: C.C.Liu
;
; Release Date: 1994.07.05
;
; Changed File: EXE/PNPPD.COM
; SOURCE/PNPPD.ASM
; SOURCE/TAIL.ASM
;
; Reason: 1. Processing parameters about commnd line.
;
; 2. Add help option -h .

pause_ macro
; jmp $+2
;
; The reason for the pause_ macro is to establish a minimum time between
; accesses to the card hardware. The assumption is that the fetch and execution
; of the jmp $+2 instruction will provide this time. In a fast cache machine
; this may be a false assumption. In a fast cache machine, there may be
; NO REAL TIME DIFFERENCE between the two I/O instruction streams below:
;
; in al,dx in al,dx
; jmp $+2
; in al,dx in al,dx
;
; To establish a minimum delay, an I/O instruction must be used. A good rule of
; thumb is that ISA I/O instructions take ~1.0 microseconds and MCA I/O
; instructions take ~0.5 microseconds. Reading the NMI Status Register (0x61)
; is a good way to pause on all machines.
;
; The National 8390 Chip (NIC) requires 4 bus clocks between successive
; chip selects (National DP8390 Data Sheet Addendum, June 1990 -- it took them
; long enough to figure this out and tell everyone) or the NIC behaves badly.
; Therefor one I/O instruction should be inserted between each successive
; NIC I/O instruction that could occur 'back - to - back' on a fast cache
; machine.
