The ATAPI floppy worked for me.
Well, actually, let's say it didn't work worse than in 2.0.5R :-)
I've three major concerns about ATAPI CD-ROM support:
1) I've never been able to use the CD-ROM after a soft reset
(i.e. #reboot ). After a cold boot, all works fine: after a reboot,
the probe is as usual, but the PC hangs while mounting /cdrom.
Actually, the probe itself gives an 'Unknown phase' error, but
it's not fatal.
2) It's not possible to use the IDE CD-ROM as the secondary
device on the IDE BUS if the master device is not present:
I know this is conceptually right, but the CD-ROMs ship
jumpered as slave by default, and often they come with an
additional secondary IDE controller on which they are the
only device. I know it hurts, but all flavours of Windows support
this configuration. I've tried to hack myself the driver, but I
concluded the job is not in my capabilities :-( (basically,
don't know enough FBSD & ATAPI internals: in fact,
I gave up when I started experiencing strange lock-ups,
but I hadn't still figured out point 1) ....)
3) (but this is probably more abuot cd9660) Multisession
capabilities are ignored: it always reads the first session.
(I'm using a CD-Recorder as fast access storage for rarely
used stuff, and I often burn multisession CDs)
My PC is a no-name chinese 486 DX/2 66 VLB motherboard,
20MB ram, S3 805 VLB VGA, VLB dual IDE controller, WD 1.2GB
IDE HD, two old 85 MB & 170 MB WD HD that were laying around
in my office. Most of the large disk is NTFS, but I have a 250 MB
FAT and a 200 MB FreeBSD 2.0.5 partition (which I try to have
fun with after a whole day of WinNT :-)
I attach dmesg output & kernel config for your reference.
Hope this helps someone of you REAL hackers.
(BTW: do you really manage to have a job, to hack so much
BSD in your free time, and to have a private life ??? :-)
