confirmed: the model 850 rom supports the GT10, which i'm pretty sure is a WD90C00. Interesting that this rom also includes support for the s3 aurora in the model 860. (this is an 850 specific v1 firmware update off pccbbs).0x000e1af0 000007b8 00000000 49424d20 506f7765 ........IBM Powe0x000e1b00 72205365 72696573 20473130 20477261 r Series G10 Gra0x000e1b10 70686963 73204164 61707465 72204472 phics Adapter Dr0x000e1b20 69766572 00000000 49424d20 506f7765 iver....IBM Powe0x000e1b30 72205365 72696573 20473130 20477261 r Series G10 Gra0x000e1b40 70686963 73204164 61707465 72000000 phics Adapter...0x000e1b50 00000818 00000000 49424d20 52532f36 ........IBM RS/60x000e1b60 30303020 47543230 20566964 656f2044 000 GT20 Video D0x000e1b70 72697665 7220666f 72203836 434d3635 river for 86CM650x000e1b80 00000000 49424d20 52532f36 30303020 ....IBM RS/6000 0x000e1b90 47543230 20383643 4d363520 50434920 GT20 86CM65 PCI 0x000e1ba0 41646170 74657200 000007a8 00000898 Adapter.........

i think i found the pci query. it's basically the same as the 860 rom.watching the 850 try to figure out whether it has a gt10.

repeatedly reading vga ctr at 00006e40 [001a] read 08 (Feature Control 3da)probably trying to detect and unlock the wd itself.fairly certain it'll boot if i can fake enough of the unlock sequence of the wd vga chip.

as far as the docs suggest, there don't seem to be nearly the acceleration features of the s3 chip. it seems there's a straight-forward update of the ega work register for 8 bit, 1 plane video if i'm reading it right.

without s3 "through the plane" writes, scrolling in personal power dos is a bit slower.

since i wrote it, i'm gonna try to boot os2 on it. i think os2 was only released for model 850.also gonna try nt on it to see if it needs anything else. i think it'll be slower but won't have the graphical bugs i still need to fix in my s3 card.

i had taken over "vga" before, but now there are separate vga, 86mc65 and wd90c00 devices. i need to deduplicate code but lazy rn.

arc151 also comes up on the wd vga.might try earlier arc just out of curiosity (they don't support the s3 vga but might support the smaller one).

hmm os2 is looping reading 8001f01d. it uses the fancy microkernel address scrambling mode of the eagle, which tries to make each block of 32 addresses in isa space be 1 page apart. the idea is that then you can access control individual pages for non-supervisor mode microkernel drivers. this doesn't work well because in practice isa space is full of weird compromises (a great example is that 3f6 is owned by the floppy controller, except for 1 unimplemented bit, which is owned by the ide controller).

that's 3fd. i recognize this, as it's waiting for a break-in from the serial port. wierdly, unlike when booted on a model 860, it didn't produce output or do any other destructive operations on the port that would cause gxemul to start an xterm. i wonder if that's because it recognized the video card.

it's waiting for transmitter empty, which nothing initialized yet.

with one hack, os/2 is accessing the scsi device to auto-boot in the 850 personality. it has never tried this before.SCSI Disk 3: command failed, status = 0, msg_in = 7

will have to figure out what from the adapter's perspective should be different between how aix does this and os/2.

it'd be pretty ironic if i wind up getting an os/2 install before aix.

it does test_unit_ready a bunch of times (maybe it doesn't like the reply?) then tries 01h, rezero_unit. no idea why yet.

if there's one thing i now know it's that no 2 oses use scsi the same way.

arc149 does work, but it wants to change the row stride and i don't know how that works on this vga yet. will have to fix it if i want to try booting nt 3.1 or nt 3.51 eventually (and probably for other stuff that uses this vga).
