IBM-DJNA drives on FreeBSD
I'm about to install FreeBSD 3.2 on a machine with an IBM-DJNA-371350 (Deskstar 22GXP 13.5GB) drive. I see that on the -current mailing list a few weeks ago you (phk) said: >Try disabling "ultra DMA" in the BIOS, that seems to have worked for >me on my IBM-DJNA-371800 drive. Is that relevant for 3.2 as well as current? And by "disabling ultra DMA" did you mean "disabling UDMA66" or "disabling UDMA completely"? (You can permanently disable UDMA66 with a DOS utility available from IBM, and it will then act as a plain UDMA33 drive.)

Re: IBM-DJNA drives on FreeBSD
> Depends on your motherboard. Try to just disable UDMA66 first. Thanks, that's what I did. It works fine (I'm using a SOYO 5EHM motherboard with an AMD K6-2/200).

Not bad for a disk costing £165 for 13.5GB. On the other hand the system really grinds to a halt while the benchmark is running. Incidentally, I tried bonnie on an MSDOS partition (just because it's at the outside of the disk) and the result was: svax32im 100 8940 89.2 12984 76.1 473 2.8 9108 92.1 15584 86.4 76.3 48.8 Note the abysmal rewrite speed! -- Richard To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

5.0 DP2 on Vaio Z600
I'm trying to install DP2 on a Sony Vaio Z600TEK laptop, but it hangs at "Probing devices, please wait (this can take a while)...". It's not completely hung, in that I can switch to the second console and back. The last message there is DEBUG: Add mapping for /dev/cuaa0 to sl0 and this is after a bunch of errors about da0:umass-sim0 (the memory stick slot, which doesn't have a card in it).

DP2 root partition size
Somewhere there should be a warning that the root partition needs to be *much* bigger in 5.0 than in 4.x. It's gone from 40-something MB to 92 MB for a default install.

I've had this problem for months if not years, in all recent releases of FreeBSD. It's not consistent, sometimes (like right now) I can run xine dozens of times without getting an error, other times I have to run it six times before it works.

Otherwise fee = malloc(n * sizeof(struct foo)) wouldn't work. C89 says: There may also be unnamed padding at the end of a structure or union, as necessary to achieve the proper alignment were the structure or union to be an element of an array. And: the result [of sizeof] is the total number of bytes in such an object, including internal and trailing padding. So if a struct needs padding in an array, it has it even when it isn't in an array. -- Richard To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

It must be the case that sizeof(struct foo) == (((char *)&fee[1]) - ((char *)&fee[0])) If that's what you meant, you seem to be saying the opposite. > and that inter-structure padding depends on ordering of elements Yes, though it isn't "inter-structure" padding, it's padding that is part of the structure. > (for a good example of this, see the struct direct name element > reference macro, which is also padding independent). Not sure which macro you mean here, since there are several variants of it which work in different ways. The one in dirent.h (I'm looking at 4.6 here) subtracts from sizeof, while the one in ufs/dir.h uses &(0->d_name) which is equivalent to offsetof. > Basically, end-padding happens because arrays of structures need to > have their first element properly aligned, so there is a pad added > after each element to ensure that the following element starts on > an alignment boundary. The point is that there isn't a pad *after* each element. The pad is part of the element, and is there regardless of whether the structure is in an array. Again, if that's what you meant you seem to be saying the opposite! -- Richard To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Re: aout support broken in gcc3
> yes binary support will remain.. if you need to generate new ones (?) You say this as if no-one would want to do it, but I still use programs (lisp and prolog compilers) that need to generate and read in compiled .o files, and "undump" themselves after reading in such files, and which are never likely to be updated to know about (the much more complicated) elf format. -- Richard To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

False. As I said, I have systems that read a.out format object files and they would need to be ported to read ELF object files instead. Furthermore, they write themselves out (after loading object files) in a.out format, and would need to be ported to write themselves out in ELF format. -- Richard To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

They compile Lisp (etc) to a C file, which they compile (with gcc) to a .o file, then link against the running image (with /usr/libexec/aout/ld -A) to produce a relocated .o file, then read it in and look at its symbol table to find the entry points. So they need a C compiler that can generate a.out format .o files, and a linker that can link a.out format .o files against an a.out format executable. I'm quite expecting the answer "yes, we've considered this and decided that the overhead of supporting it is to much", but I want to make sure that you realise that there are programs that will break. Long-time BSD users will not be surprised to know that Franz Lisp (the original BSD Franz Lisp, not the commercial Franz Inc product) is one of them. Incidentally, I know that the "modern" alternative to reading in .o files is to use shared libraries instead, but as far as I know there isn't any support for writing out an executable that has shared libraries mapped in (so that they don't have to be loaded, or even exist, when the program is started again). -- Richard To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Re: aout support broken in gcc3

That would be sufficient for my needs (a matching gdb would be useful too, I'm not sure if that is part of binutils). But I don't think my concern was misplaced: having gone back through the thread for the past couple of weeks, there were certainly phrases like "drop all traces of a.out support" "if you need to generate new ones (?) unpack a 2.2.6 system" with the ports solution mentioned only "if we really have to have a.out". -- Richard (running Franz Lisp since 1983) To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
