Disklabels are still there, ! 216: but are fairly meaningless to the kernel (except for the basic ! 217: geometry information from the BIOS). ! 218: ! 219: * kernel/i386at/disk.h: minor addition of BAD_BLK from the ! 220: old hdreg.h file (which is gone) ! 221: ! 222: * kernel/i386at/pchd.c: removed as obsolete ! 223: ! 224: * kernel/i386at/hdreg.h: removed as obsolete ! 225: ! 226: Tue Feb 13 16:22:48 1996 steve clawson <[email protected]> ! 227: ! 228: * kernel/i386at/if_ne.c: Changed initialization code to follow the ! 229: National Semiconductor guidelines for setting up the 8390. ! 230: ! 231: Sun Jan 28 22:56:38 MST 1996 Bryan Ford <[email protected]> ! 232: ! 233: * Checked in major MOSS changes from work at home: ! 234: got DPMI support working (Win 3.1, Win95, OS/2) ! 235: modulo a few minor incompatibilities; ! 236: VCPI and DOS support are fully functional (again); ! 237: VCPI and DPMI now support fastints. ! 238: ! 239: Wed Jan 17 17:18:57 1996 Bart Robinson <[email protected]> ! 240: ! 241: * Serial console working for real. ! 242: ! 243: * kernel/bogus/rc.h: removed RCBAUD and added RCADDR, prettied up. ! 244: ! 245: * boot/serial.S: added. This is used by the boot adaptor part, ! 246: the rest of the kernel uses mach4/kernel/device/cons.[ch]. This ! 247: file was taken from FreeBSD who took it from Mach sometime. ! 248: ! 249: * kernel/pc/putchar.c: changed to use serial.S if <rc.h> says so. ! 250: ! 251: * boot/bsd/Makerules: serial.S needs kernel/bogus to be on the -I ! 252: list ! 253: ! 254: * boot/linux/Makerules: ditto ! 255: ! 256: * kernel/i386at/model_dep.c: changed to call cninit() rather than ! 257: kdinit().

The console is handled ! 261: differently now. ! 262: ! 263: * kernel/i386at/conf.c: console entry in the device list is now ! 264: the `virtual' one "cn" instead of "kd" ! 265: ! 266: * kernel/i386at/cons_conf.c: added. Defines the constab array ! 267: which tells us which console-like things to look for. ! 268: ! 269: * kernel/i386at/com.c: tweaked to export an interface that ! 270: mach4/kernel/device/cons.[ch] wants. RCBAUD is in here now ! 271: rather than rc.h. ! 272: ! 273: * kernel/i386at/kd.c: ditto ! 274: ! 275: Wed Jan 17 13:51:46 1996 Kevin Van Maren <vanmaren.cs.utah.edu> ! 276: ! 277: * Unified the partition code for IDE & SCSI device drivers ! 278: ! 279: * kernel/i386at/pc_label.c: deleted ! 280: * kernel/i386/pc_hd_label.c: deleted (used by hd.c) ! 281: * kernel/i386/hd.c: deleted (old 'ide' driver) ! 282: ! 283: * kernel/i386at/nhdreg.h: Removed the definition of PDLOCATION, ! 284: should be in <i386at/disk.h> not here! ! 285: ! 286: * kernel/i386at/nhd.c: Removed IDE specific PC partition code. ! 287: Changed to use the unified partition code. ! 288: ! 289: Mon Oct 30 08:33:01 1995 Bryan Ford <[email protected]> ! 290: ! 291: * mach4-i386/kernel/i386at/interrupt.S: from Shantanu: proper fix ! 292: for interrupt disable bug. ! 293: * mach4-i386/kernel/i386/spl.S: likewise. ! 294: ! 295: Mon Oct 23 11:08:33 1995 steve clawson <[email protected]> ! 296: ! 297: * bootstrap/translate_root.c: new file ! 298: bootstrap/translate_root.h: likewise ! 299: ! 300: Code to convert strange root device encodings (like Linux device ! 301: numbers) into what Mach wants. ! 302: ! 303: Sun Oct 22 18:36:49 1995 Bryan Ford <[email protected]> ! 304: ! 305: * Integrated Steve's and Bart's changes from the UK02p16-work branch. ! 306: ! 307: * boot: updated booter/kernel interface to be (mostly) conformant ! 308: to MultiBoot-0.3 proposal. ! 309: ! 310: * boot/bsd/crt0.S: pass a boot loader value (Mach/NetBSD/FreeBSD) ! 311: as well as boothowto and bootdev. ! 312: ! 313: * boot/bsd/main.c: Fabricate a proper MultiBoot kernel command line ! 314: from the boothowto and bootdev values. ! 315: ! 316: * boot/bsd/main.c: Cleaned up symbol table loading, so it should ! 317: work with all a.out format variants. ! 318: ! 319: * boot/bsd/main.c: Provide the kernel info on the device we booted from. ! 320: ! 321: * mach4-i386/kernel/i386at/model_dep.c: MultiBoot-0.3 compliance. ! 322: ! 323: * mach4-i386/kernel/i386at/interrupt.S: mostly fix interrupt nesting ! 324: problem with Linux driver changes. ! 325: ! 326: Mon Oct 16 14:49:01 1995 steve clawson <[email protected]> ! 327: ! 328: * boot/bsd/crt0.S: Now should be able to differentiate between ! 329: the original Mach bootblocks, the old BSD (which NetBSD uses) ! 330: bootblocks and the new-style FreeBSD bootblocks. ! 331: ! 332: Fri Oct 13 16:59:10 1995 steve clawson <[email protected]> ! 333: ! 334: * boot/boot_info.c: Add code to add the symbol table into the ! 335: occupied list that we hand to the kernel. ! 336: ! 337: * boot/bsd/crt0.S: Added in code to pass along the boothowto and ! 338: bootdev. We should be able to tell between Mach, FreeBSD and ! 339: NetBSD bootblocks, but we don't tell anyone about it yet. ! 340: ! 341: * boot/bsd/main.c: Now tries to find the kernel symbol table and ! 342: put it into a `safe' place for the kernel to grab later. It ! 343: also sets the bsd_boothowto and bsd_bootdev fields of the ! 344: boot_info struct. ! 345: ! 346: * bootstrap/exec.c: Enabled code to load symbol tables. ! 347: ! 348: * kernel/i386/setroot.c: Changed code to work with BSD bootblocks ! 349: (and their major device numbering...sd == 4, instead of 3). ! 350: ! 351: * kernel/i386at/model_dep.c: Now sets kern_sym_start and ! 352: kern_sym_size from boot_info, along with boothowto and ! 353: bootinfo from the bootblocks. ! 354: ! 355: Wed Oct 4 20:04:27 MDT 1995 Bryan Ford <[email protected]> ! 356: ! 357: Released moss-0.80 (tag moss-0-80) ! 358: ! 359: Wed Oct 4 12:05:57 MDT 1995 Bryan Ford <[email protected]> ! 360: ! 361: Merged in changes made for DOS extender at home: ! 362: * added mach/i386/debug_reg.h, ! 363: containing definitions for accessing the debug registers. ! 364: * changed i16 code to add physical memory to the malloc pool ! 365: (assuming we're using the lmm to handle the malloc pool). ! 366: ! 367: Tue Oct 3 13:22:50 1995 steve clawson <[email protected]> ! 368: ! 369: * kernel/pc/i16/i16_raw.c: baford's changes to work with gcc ! 370: 2.7.0. ! 371: boot/boot_start.c: Likewise. ! 372: ! 373: Thu Sep 28 17:37:44 1995 steve clawson <[email protected]> ! 374: ! 375: * Makefile.in: added image, bsdimage and linuximage targets. ! 376: image will build both the linux and bsd images (Mach and zMach), ! 377: in the Object directory, the others will only build their their ! 378: respective images. ! 379: ! 380: * kernel/bogus/hpp.h: Changed #define to be 1, so that the driver ! 381: is included by default. ! 382: ! 383: * kernel/i386at/autoconf.c: Changes for NE2000. ! 384: kernel/i386at/conf.c: Likewise. ! 385: kernel/i386at/if_ne.c: NE2000 driver. ! 386: kernel/i386at/if_nereg.h: NE2000 driver header file. ! 387: ! 388: * kernel/i386at/gpl/if_hpp.c: Changed #include of vm_param.h to ! 389: "vm_param.h", since it wasn't getting found in the usual place. ! 390: kernel/i386at/gpl/if_ul.c: Likewise. ! 391: kernel/i386at/gpl/if_wd.c: Likewise. ! 392: ! 393: ! 394: Fri Aug 25 23:39:19 1995 Shantanu Goel <[email protected]> ! 395: ! 396: * kernel/i386/hardclock.c: (cold): Deleted.

One side-effect of this is that the ! 712: 32-bit boot images produced by this script will be in the ! 713: "native" executable format of the build environment in use. ! 714: For example, if you build under NetBSD, the produced 32-bit ! 715: boot images will load fine from BSD boot blocks, but probably ! 716: not from Mach boot blocks, because the Mach boot blocks don't ! 717: know about BSD's newer a.out format. ! 718: ! 719: * Enabled SCSI drivers. ! 720: ! 721: * God kernel debugger working again. ! 722: ! 723: * Changed kd.c to handle tabs correctly. ! 724: ! 725: Fri Sep 30 21:38:31 1994 Patrick Doyle (wpd@peanutbutter) ! 726: ! 727: * Makefile.in ! 728: (SORTED_SUBDIRS): ! 729: Added a macro to generated a "sorted" list of subdirectories ! 730: such that those listed in $(FIRST_SUBDIRS) are first.
