Win95 Hanging due probably to Adaptec 2940
Posted on 1998-03-22
After an extended period of time (over an hour and less than 8 hours) my pc
will suspend (I believe) disk activity screwing up whatever is running at the
time. This screwing up could include anything from stopping downloads to
locking up my machine due to screen saver running siezing. This last one
finally pissed me off in that it made me HardBoot and ended up destroying
my Video Driver.
I have Win 95 OEM2 on a P-Pro 200Mhz and 128MB RAM.
I have an Adaptec 2940 SCSI host adapter with Bios 1.25 (as recomended) on it
on SCSI ID 7. I used EZ-SCSI 4.0 to support the adapter.
2 Quantum 4GB SCSI hard drives hang off it with Win95 wishfully on SCSI ID #6
and an empty drive slated for Red Had Linux 5.0 on SCSI ID#5 all
Other stuff include SCSI CD ROM and DAT Tape backup and Hercules Thriller 3D
It seems that ever since I played with EZ-SCSI 4.0's disk spin down parameters to
set it to go off after so many hours, it never seemed to turn off. I could
be wrong with this as I am in bed when problem arises, but all points to
Another thing that makes me wonder is another problem related possibly to the 2940
adapter. I tried to partition my disk for Red Had 5.0 and attempted to load it.
It seemed to load ok, but when tried to reboot, it seemed to change the
partition id's to a number 10 greater than they should be...I think this is a
technique used for hiding files/partitions somehow. I am using System
Commander 3.09 to allow me to primary boot Win95 and secondary boot
the Linux with Master boot record in first partition and not the master boot
I am confused by this point and don't know what to do next to remove this problem as
I am not an exptert in 2940 type problems and don't know why disk partitioning
and disk stopping even though all seems set up correctly. In another experts
discussion I had learned that the newer version of Adaptec worked most
efficiently by making most used devices close to SCSI Adapter SCSI Id.
Thank you for any help you can give. If there is any information I can give to help with
understanding or fixing, please let me know.
