README of IDE386.EXE
This README file of IDE386.EXE accompanies IDE.DSK for NetWare v3.11.
This driver supports most IDE drives with Netware v3.11. Along with other
IDE drives, this driver specifically supports the IBM PS/2 models 35 and
40. This version of the driver has been enhanced to be more robust in
handling error conditions. Previous versions may have permitted drive
de-activation under conditions which will now be addressed as media errors.
The media errors will cause Hot Fix to re-direct and the drive will stay
active rather than be de-activated.
A rare, but possible problem, was addressed that could cause a server to
hang under the following conditions:
1. Heavy server load
2. The console operator, within MONITOR.NLM, activates a previously
de-activated device.
INSTALLATION INSTRUCTIONS:
To install this Disk Driver:
1) Copy IDE.DSK to the boot-up directory of the server. (Same location
as your SERVER.EXE)
2) After the system is brought up, example: LOAD A:IDE.DSK
NOTES:
The IDE disk driver was written to work with ATA/IDE disk drives. The
ISADISK driver should not be used with these disk drives. This driver is a
self configuring driver and does not rely on the BIOS for disk drive
support.
The driver supports Read-after-write verify at the software level. Using
the VERIFY ON mode will cause writing to the disk to be a little slower
than normal.
The driver will also support up to eight ATA/IDE disk drives in a file
server. This is possible by using addressable paddleboards. These
paddleboards allow the user to configure the base I/O address and IRQ.
(Primary I/O address at 1F0h and IRQ 14, second address at 170h, third
address at 1E8h, and fourth address at 168h.) IRQs 9, 10, 11, and 15 may
be used with the second, third, and fourth base I/O addresses. It is not
recommanded to use IRQ 12 because of possible conflicts with the mouse
port.
Not all paddleboards will work correctly in all file servers. Refer to
your hardware manufacturer or system integrator for recommended
configurations.
LIMITATIONS:
* The IDE disk driver will not work with ESDI and the ST506/412 bus
controllers. The ATA/IDE, ST506, and ESDI interfaces look similar to the
system software; however, they are handled differently by the disk driver.
* If a disk drive is to have a DOS partition installed, it will need to be
installed BEFORE the NetWare partition is installed.
