Subject: Installing FreeBSD 2.1 from DOS gets errors while accessing files
Sender: owner-bugs@FreeBSD.org
Precedence: bulk

I have a VERTOS atapi CD-rom on a secondary IDE port (170h Irq 15).
That CD-ROM does not work under FreeBSD so I tried DOS installation instead.
The system is a 486 DX4 (100Mhz) with VLB bus, 2 IDE HD's on primary IDE
(WD 850Mb + WD 200Mb) while the secondary IDE is for the CD-ROM.
There is a primary DOS partition of 250 Mb where I xcopy'ed the FreeBSD files
from the CDROM (C:\FREEBSD\FLOPPIES, C:\FREEBSD\BIN, etc...).
After booting (either from DOS or from the boot-floppy) and having completed
all the path along the "NOVICE" installation, I select the installation media
to be the DOS partition, after which:

   -- initial phase before accessing data from C:\FREEBSD seems perfectly OK,
   -- checksum errors are then reported as soon as C:\FREEBSD\BIN data are
      first accessed... every other DOS file then causes errors during read.

I tried many different things, like NOT mounting the DOS partition during
disk LABELling phase, or just the opposite, or activating/deactivating
IDE block-transfer mode in the board and IDE adapter BIOS, without success.

Also, although I have a modem-adapter installed as port 3E8 Irq 5, as
supposedly defined in the FreeBSD kernel, this device is never detected.

Could the Soundblaster 16 (IDE) card (no CD-ROM) be causing troubles?

Thanks a lot for your help.
