Allow specifying the BIOS drive number. Removed the hd drive type. hd essentially wired the FreeBSD drive number to 0 without changing the BIOS drive number. Now the numbers can be specified independently. Replaced the BOOT_HD compile time flag with with BOOT_HD_BIAS. Defining the new flag as 1 should give the same behaviour as defining the old flag as anything. I haven't tested defining these flags.

1. Completely rewritten Makefile that uses bsd.prog.mk more effectively. 2. Clean up the .S files to use /* */ style comments. This is a totally cosmetic change, not one byte of the resulting boot code changes. But at least it is installed with correct owners and in the right places, and gets recompiled correctly when things change!

# Order is very important on the SRCS line for this prog
Submitted by: Bill Paul (wpaul@ctr.columbia.edu) Obtained from: bios boot block changed to allow booting from both the attached graphics display and from a serial port. (A specially compiled serial boot block is no longer necessary.) The boot block should detect the presence or absence of a keyboard: if there is no keyboard, COM1 is turned into the console. This simulates the behavior of the Sun boot PROMs. Unplug your keyboard, attach a terminal to COM1 and you should be ready to go. :)

Implement an optional TIMEOUT value while entering the boot parameter string. This avoids indefinite hangs e.g. when used on a noisy serial console. It's not turned on by default.

1. BOOTSEG and BOOTSTACK are now set from the Makefile, the boot code has been relocated to run in the 64k segment at 0x10000 with the stack at the top of this segment. This corrects the problems machines with 512K base memory had booting. 2. startprog routing rewritten to convert the BOOTSEG ss to a KERNELSEG ss, this eliminated the last of the >512K memory references. Additional cleanup in here included a better way to copy the arguments to the kernel stack. 3. Elimination of argv and esym cruft saved a few bytes. 4. Only need to truncate the head.a_entry to a meg boundary once intead of every time we used it! [Saving more bytes]. 5. Addition of version 1 bootinfo structure support. These boot blocks pass the kernel name in to the kernel now. 6. Removed historical comments about MACH argv stuff, as it is useless now.

Boot block cleanup. o Fix the keyboard probe to properly wait for the ready bit before sending a command to the keyboard controller. This should avoid the problems some people are experiencing where the boot blocks hang the system during keyboard probe. (It does solve it for me.) o Fix a bug that effectively prevented the boot blocks from ever passing control to the serial console. [while(--retries) instead of while(retries--)] o Gratuitously reduced the keyboard probe timeout from 500 to 5 seconds. :) o Introduced a new option ``FORCE_COMCONSOLE'' as a commented-out example in the Makefile, to force the usage of a serial console regardless of a keyboard being connected or not. o Moved all external declarations to boot.h, declared all functions there, and ANSIfied all function declarations/definitions. (printf() remains bogus, however -- i'm too lazy to fix this.) We're in the ninetees, dunno why we should still support compilers from the 70's.

Probe the keyboard if PROBE_KEYBOARD is defined instead of when `notyet' is defined and FORCE_COMCONSOLE isn't defined. Don't compile any keyboard probing code if PROBE_KEYBOARD isn't defined. Makefile: Removed -I paths. They weren't used, and the one to /sys hasn't worked since the source directory was moved down one level.

. Make Poul's boot2 overflow warning less noisy in case the blocks do fit, and beeping in case of an overflow. . Drop a comment about the ``FORCE_COMCONSOLE'' option into README.serial. . Increase the name buffer for the root directory from 100 bytes to 8 KB; this is in no way ideal, but (IMHO) the best that can be done by now. People did encounter problems with their root dir name listing overflowing the allocated buffer space. Once we've got the three-stage boot, we should implement some basic malloc(). Swap space is already getting tight now, perhaps the swap should go into another 64 KB segment instead. . Make the keyboard probe less paranoid. It should not give up in case of a keyboard that's continuously demanding RESEND's. Even though the keyboard reset apparently has not been reported to be complete, it's at the very least proven that there IS something like a keyboard available. This solves problems with the ``Gateway-2000 AllKey programmable'' (sp?) keyboard, that experienced a total hang with the previous probe. Thanks goes to Scott Blachowicz <scott@statsci.com> for his extensive testing of my various interim (debugging) bootblocks to get this working.
