; Change History (most recent first):
;
; <SM3> 6/14/93 kc Roll in Ludwig.
; <LW4> 5/14/93 fau This delay is still not right. While I get the source for the
; latest ROM for this card, I'm upping the delay to 5ms and doing
; a Nubus read in between rights, to flush the MUNI FIFO's.
; <LW3> 5/14/93 fau Put a delay in writing to Endeavor so that it works with
; Cylone40. It looks like MUNI is writing out the data too fast!
; <LW2> 4/27/93 fau Bug #1081554: Added an extra delay before starting JMFB, so
; that they work on Cyclone 40MHz.
; <SM2> 11/18/92 SWC Changed SlotEqu.a->Slots.a and VideoEqu.a->Video.a.
; <2> 1/15/92 KC Repair "uncompleted conditional directive" error. Removed
; gratuitous branch.
; <1> 1/7/92 RB first checked in
; =============== Terror History ========================
;
; <4> 6/17/91 jmp Eliminated support for PAL displays & encoder boxes since the
; versions of the 4•8 & 8•24 cards that we’re patching out don’t
; have the sRsrcs.
; <3> 4/4/91 jmp Cleaned up the conditional assembly stuff (i.e., started using
; ForRom instead of PadForOverPatch).
; <2> 2/25/91 jmp Rolled in Casey’s latest changes.
; <1> 01/06/90 jmp Checked into TERROR ROM for the first time.
; <0> 11/19/90 jmp Formatted for use with TERROR ROM (as opposed to a
; declaration ROM).
;
;-------------------------------------------------------------------
;
; This file contains the primary initialization code for the Elmer
; Fudd video ROM and is included by ElmerROM.a. The purpose of the
; primary initialization is to detect the monitor type in use and the
; memory available so that the appropriate sResource list can be selected
; and the others discarded. In addition the the display device is setup
; for 1 BPP operation by setting the color lookup table to black and white,
; initializing the hardware for 1 BPP and then graying the screen.
;
; Notes:
; ------
;
; 1. The basic flow of the primary initialization code is as follows:
;
; Start
; Header Information
; Set Initial Vendor Status to good
; Form 32 bit slot base address
; Setup a slot parameter block for sRsrc pruning
; Check to see which slot mgr is around and save
; Decode sense lines to detect monitor type
; Setup Mode to be Disabled to invalid
; Get saved monitor type from parameter RAM
; Init the inval screen flag to false
; If monitor type is different then invalidate scrn resource flag
; If ntsc then determine oscan/uscan state and if changed then inval scrn flag
; Size video RAM and set VRAM configuration bit
; Form the spID candidate to disable
; If Inval scrn then save new mode in pram
; Remove Invalid sRsrc Lists
; Setup Hardware
; Disable Interrupts (card resets disabled!)
; Setup CLUT for 1 BPP
; Gray the Screen
; End
;
; 2. Monitor Sensing
;
; The raw monitor sense lines read in are reformatted to facilitate sRsrc pruning
; and the following table summarizes the raw sense line combinations and the
; the reformatted ones. The RGB Kong monitor is the only one that is reformated.
; The 2 least significant bits of the sRsrc IDs (see ROM.a header comments) are
; idenitical to the 2 least significant bits (b1:b0) of the reformated sense line
; combination and b2 of the sense line indicates whether its RGB or B/W.
;
; Sense(2:0) Raw Reformatted Sense Monitor Type
; -------------- ----------------- -------------
; 000 111 RGB Workstation (Kong)
; 001 001 B/W Full Page (Portrait)
; 010 010 Modified Apple II-GS RGB (Rubik)
; 011 011 B/W Workstation (Kong)
; 100 100 NTSC (Interlaced)
; 101 101 RGB Full Page (Portrait)
; 110 110 Standard RGB
; 111 000 No Sense read (unconnected)
;
; There are a couple of interesting relationships that we can take advantage of from
; the reformatted sense line combinations:
;
; a) Kong or Portrait = b0
; b) Other = not b0
; c) Kong timing = b1 and b0
; d) Portrait timing = not b1 and b0
;
; In addition to the traditional monitor sensing that we have normally done, this
; card also utilizes Rosko's extended sense scheme. We use this only to detect if
; the Sarnoff breakout box is connected and if it is we will always default to
; the RS170 timing mode. This will enable us to at least use the box as an RGB
; to NTSC encoder when it arrives.
;
; 3. Pruning
;
; Refer to the comment in the code.
;
; 4. Hardware setup sequence
;
; a) Setup CLUT pixel bus control register
; Setup JMFB CSR except for REFEN, VRSTB, and VIDEN
; Setup JMFB Load Divisor Register
; Setup JMFB Base Register
; Setup JMFB Row Long Words Register
; b) Set up the Endeavor chip (M,N, and EXTCLK)
; c) Enable the Endeavor clock by set PIXSEL1 in the JMFB CSR
; d) Delay to guarantee a stable clock from Endeavor
; e) Enable JMFB by setting VRSTB in JMFB CSR
; f) Setup Stopwatch parameters (must happen after VRSTB is set because
; that also reinitializes Stopwatch!)
; g) Enable Stopwatch by setting SRST
; h) Enable REFEN in JMFB CSR
; i) Enable Video Transfer Cycle in JMFB CSR
;
; 5. 24 Bit addressing and 32 bit addressing
;
; This card is not accessible in 24 bit addressing mode and all accesses must be made
; in 32 bit mode when hitting the hardware. That's explains the frequent use of
; SwapMMUMode to switch back and forth. It is not desirable to access a 32 bit
; address in 24 bit mode as we will not go where we want to!!!
;
; 6. Trident use of PRAM
;
; This card uses pram as follows:
;
; byte 0, 1 -> board ID
; byte 2 -> mode (screen depth)
; byte 3 -> saves the default sRsrcID (changed by SetDefault)
; byte 4 -> pinit raw sRsrcID (only modified by pinit)
; byte 5 -> specialFlag (set to $FF if connected to interlaced monitor and past shutdown mode is 32 bpp)
; byte 6 -> clockType flag (set to $00 if Endeavor and $FF if National)
;
; Register usage:
; ---------------
;
; D0 - Initially used to form the cards slot number.
; Later used as the switch ID for SwapMMUMode trap.
; Used in the vRAM test to hold test pattern.
; D1 - Used throughout as a utility register (counter or index usually).
; D2 - Used in Pruning section to form the candidate spID to be deleted.
; Used in Gray Screen to hold the number of rowlongs as a counter.
; D3 - Used to hold the spID of the mode to be disabled (interlaced modes only)
; Used in Gray Screen to hold the number of screen rows.
; D4 - Used to hold the reformated sense line combination.
; Used to form the spID based on monitor and memory.
; Used to select which parameter list to be used in hardware setup.
; Used to determine appropriate default fb base offset in grayscreen.
; D5 - Used to hold the dither pattern in gray screen.
; D6 - Used to identify if the new slot manager is present (0=new, $FF=old) .
; D7 - Used to temporarily hold previous addr state during SwapMMUMode
; - Used to count the number of sRsrcs deleted.
;
; A0 - On entry contains a parameter block pointer to an SEBlock
; Later used to point to the slot parameter block.
; Later used to point to the hardware setup parameter data.
; A1 - Used initially to point to the cards base address ($Fs00 0000).
; Used later to point to control register space during hardware setup.
; A2 - Used to point to the valid mode list during sRsrc pruning
; Used to point to the JMFB Control and Status Register during hardware setup.
; Used to point to the CLUT during color table initialization.
; Used to point to the frame buffer during gray screen
; A3 - Used to save the cards base address (A1) in hardware setup, clut setup and gray screen.

; - card is the startup screen, the card will have been temporarily reset to 1 bpp by the system before secondaryinit
; - because 32 BQD will not have been loaded yet. During that temporary period, the driver privates and PRAM (savedMode)
; - will reflect 1 bpp. This is only a problem if our card is a startup screen! UGH... The special flag is reset to false
; - initially assuming the special case won't be in effect. Note that PInit is the sole place where this flag is set and

; change monitors, but they have the same screen dimensions (like ntsc oscan and standard 13"). In the first
; case, the new sRsrc installed will only support certain valid screen depths and even if an past mode
; which is not in the new mode list is called, ChkMode will not allow the mode request. In the second case, the
; problem may result in desirable operation, since the menu bar will stick on the new monitor if it was there
; prior to the restart. (i.e. in other scenarios, like a different sized monitor, CheckDevices will invalidate
; and the main screen will go back to the card in the lower slot number).

; remove invalid sResource lists
;
; - The following section of code prunes out the undesirable and invalid sResources
; - from the sResource table. The undesirable sResources are the 24 bit sResources
; - when the new slot manager/32 BQD code is in ROM, or the undesirable sResources
; - are the 32 bit sResources when the new slot manager/32 BQD code is not present
; - or installed as a patch after primary initialization is run. Each bit in the
; - sResource ID has a meaning and it is summarized here:
; -
; - b7 = 1
; - b6 = 0
; - b5 = 1 if 1024K of vRAM, otherwise 0 for 512K of vRAM
; - b4 = 0 if 32 bit sRsrc, otherwise its a 24 bit sRsrc and b4 = 1
; - b3 = a b3, b2, b1 and b0 are used to identify monitor type
; - b2 = b b3, b2, b1 and b0 are used to identify monitor type
; - b1 = c b3, b2, b1 and b0 are used to identify monitor type
; - b0 = d b3, b2, b1 and b0 are used to identify monitor type
; -
; - b3:b2:b1:b0 = 0000 -> NTSC overscan "System 7.0" mode sRsrc
; - b3:b2:b1:b0 = 0001 -> 640 x 870 portrait monitor
; - b3:b2:b1:b0 = 0010 -> 512 x 384 modified Apple IIGS RGB monitor
; - b3:b2:b1:b0 = 0011 -> 1152 x 870 two page display monitor
; - b3:b2:b1:b0 = 0100 -> NTSC overscan mode sRsrc
; - b3:b2:b1:b0 = 0101 -> not used (reformats to 001 for RGBPortrait sense)
; - b3:b2:b1:b0 = 1110 -> 640 x 480 standard monitor
; - b3:b2:b1:b0 = 0111 -> not used (reformats to 011 for RGBKong sense)
; - b3:b2:b1:b0 = 1000 -> NTSC underscan "System 7.0" mode sRsrc
; - b3:b2:b1:b0 = 1001 -> not used (defaults to 0001)
; - b3:b2:b1:b0 = 1010 -> not used (defaults to 0010)
; - b3:b2:b1:b0 = 1011 -> not used (defaults to 0011)
; - b3:b2:b1:b0 = 1100 -> NTSC underscan mode sRsrc
; - b3:b2:b1:b0 = 1101 -> not used (defaults to 0001)
; - b3:b2:b1:b0 = 1110 -> not used (defaults to 0110)
; - b3:b2:b1:b0 = 1111 -> not used (defaults to 0011)
;
; - Once _sVersion is called, we know which version of the slot manager we have and
; - all of the undesirable sResources (determined by the mode list, b7, and b4) will
; - be deleted.
; -
; - After the undesirable sResources are removed, the invalid sResources are handled as in
; - previous Apple ROMs where the current mode (as determined by the monitor sense test and
; - vRAM test) is in the low 4 bits of D4 (see b3:b0 above). The current mode is compared
; - to all allowable modes and the invalid ones are deleted and the lone valid one is left.
; - Note that b2 is of no importance at this time and it is cleared prior to the comparisons.
; -
; - Refer to the Video Configuration ROM Software Specification (3/15/89) for details on the
; - goofy things required to play in a 32 bit world!!
