I actually wrote a perl script for this until I realized that this is
impossible (bang head on desk). There are about 490 directories in my
version of the Driverpacks (may be a month old or so). In my condensed
version, I need about 2 characters per directory. Since everything
starts with D\ and ends with ;, this is about 5 characters per
directory, or about 2500 total.
My version of the OemPnPDriversPath generated by my perl script was (sorry for
the long line):
D/0;D/1;D/2;D/3;D/4;D/5;D/6;D/7;D/8;D/9;D/a;D/b;D/c;D/d;D/e;D/f;D/g;D/h;D/i;D/j;D/k;D/l;D/m;D/n;D/o;D/p;D/q;D/r;D/s;D/t;D/u;D/v;D/w;D/x;D/y;D/z;D/00;D/01;D/02;D/03;D/04;D/05;D/06;D/07;D/08;D/09;D/0a;D/0b;D/0c;D/0d;D/0e;D/0f;D/0g;D/0h;D/0i;D/0j;D/0k;D/0l;D/0m;D/0n;D/0o;D/0p;D/0q;D/0r;D/0s;D/0t;D/0u;D/0v;D/0w;D/0x;D/0y;D/0z;D/10;D/11;D/12;D/13;D/14;D/15;D/16;D/17;D/18;D/19;D/1a;D/1b;D/1c;D/1d;D/1e;D/1f;D/1g;D/1h;D/1i;D/1j;D/1k;D/1l;D/1m;D/1n;D/1o;D/1p;D/1q;D/1r;D/1s;D/1t;D/1u;D/1v;D/1w;D/1x;D/1y;D/1z;D/20;D/21;D/22;D/23;D/24;D/25;D/26;D/27;D/28;D/29;D/2a;D/2b;D/2c;D/2d;D/2e;D/2f;D/2g;D/2h;D/2i;D/2j;D/2k;D/2l;D/2m;D/2n;D/2o;D/2p;D/2q;D/2r;D/2s;D/2t;D/2u;D/2v;D/2w;D/2x;D/2y;D/2z;D/30;D/31;D/32;D/33;D/34;D/35;D/36;D/37;D/38;D/39;D/3a;D/3b;D/3c;D/3d;D/3e;D/3f;D/3g;D/3h;D/3i;D/3j;D/3k;D/3l;D/3m;D/3n;D/3o;D/3p;D/3q;D/3r;D/3s;D/3t;D/3u;D/3v;D/3w;D/3x;D/3y;D/3z;D/40;D/41;D/42;D/43;D/44;D/45;D/46;D/47;D/48;D/49;D/4a;D/4b;D/4c;D/4d;D/4e;D/4f;D/4g;D/4h;D/4i;D/4j;D/4k;D/4l;D/4m;D/4n;D/4o;D/4p;D/4q;D/4r;D/4s;D/4t;D/4u;D/4v;D/4w;D/4x;D/4y;D/4z;D/50;D/51;D/52;D/53;D/54;D/55;D/56;D/57;D/58;D/59;D/5a;D/5b;D/5c;D/5d;D/5e;D/5f;D/5g;D/5h;D/5i;D/5j;D/5k;D/5l;D/5m;D/5n;D/5o;D/5p;D/5q;D/5r;D/5s;D/5t;D/5u;D/5v;D/5w;D/5x;D/5y;D/5z;D/60;D/61;D/62;D/63;D/64;D/65;D/66;D/67;D/68;D/69;D/6a;D/6b;D/6c;D/6d;D/6e;D/6f;D/6g;D/6h;D/6i;D/6j;D/6k;D/6l;D/6m;D/6n;D/6o;D/6p;D/6q;D/6r;D/6s;D/6t;D/6u;D/6v;D/6w;D/6x;D/6y;D/6z;D/70;D/71;D/72;D/73;D/74;D/75;D/76;D/77;D/78;D/79;D/7a;D/7b;D/7c;D/7d;D/7e;D/7f;D/7g;D/7h;D/7i;D/7j;D/7k;D/7l;D/7m;D/7n;D/7o;D/7p;D/7q;D/7r;D/7s;D/7t;D/7u;D/7v;D/7w;D/7x;D/7y;D/7z;D/80;D/81;D/82;D/83;D/84;D/85;D/86;D/87;D/88;D/89;D/8a;D/8b;D/8c;D/8d;D/8e;D/8f;D/8g;D/8h;D/8i;D/8j;D/8k;D/8l;D/8m;D/8n;D/8o;D/8p;D/8q;D/8r;D/8s;D/8t;D/8u;D/8v;D/8w;D/8x;D/8y;D/8z;D/90;D/91;D/92;D/93;D/94;D/95;D/96;D/97;D/98;D/99;D/9a;D/9b;D/9c;D/9d;D/9e;D/9f;D/9g;D/9h;D/9i;D/9j;D/9k;D/9l;D/9m;D/9n;D/9o;D/9p;D/9q;D/9r;D/9s;D/9t;D/9u;D/9v;D/9w;D/9x;D/9y;D/9z;D/a0;D/a1;D/a2;D/a3;D/a4;D/a5;D/a6;D/a7;D/a8;D/a9;D/aa;D/ab;D/ac;D/ad;D/ae;D/af;D/ag;D/ah;D/ai;D/aj;D/ak;D/al;D/am;D/an;D/ao;D/ap;D/aq;D/ar;D/as;D/at;D/au;D/av;D/aw;D/ax;D/ay;D/az;D/b0;D/b1;D/b2;D/b3;D/b4;D/b5;D/b6;D/b7;D/b8;D/b9;D/ba;D/bb;D/bc;D/bd;D/be;D/bf;D/bg;D/bh;D/bi;D/bj;D/bk;D/bl;D/bm;D/bn;D/bo;D/bp;D/bq;D/br;D/bs;D/bt;D/bu;D/bv;D/bw;D/bx;D/by;D/bz;D/c0;D/c1;D/c2;D/c3;D/c4;D/c5;D/c6;D/c7;D/c8;D/c9;D/ca;D/cb;D/cc;D/cd;D/ce;D/cf;D/cg;D/ch;D/ci;D/cj;D/ck;D/cl
This is 2414 characters, not even close to 1024.
I peeked in unattend.txt recently while troubleshooting something else,
it seemed like there were even less than 1024 characters in the
OemPnPDriversPath, I might try to look into this later. My ideas to
solve this:
- Only add the mass storage and LAN drivers to unattend.txt, and add the
sound/VGA/WLAN/CPU drivers somewhere in the textmode/GUI setup part.
- Use one of the original BTS methods that unpacks (we could skip the
unpacking if this would improve performance) the drivers somewhere in
the textmode setup. I don't think the 1024 character limit is a
problem in this part. Method 1 seemed the cleanest if I remember
correctly.
I didn't have time to look at implementing one of these yet. The second
seems to be the easiest solution (I believe it also adds mass storage
drivers to txtmode.inf), but the disadvantage is that you have to run
the BTS cmd file (from BTS_base) for each Windows installation (on a
Windows box), instead of just symlinking the D directory. I have not
tested this in combination with unattended yet, I believe it also
modified winnt.sif to install some auxiliary software for the drivers,
this should be done via todo.pl in unattended.
