Subject: [Bochs-developers] question about disk behavior

I am installing a linux firewall system (ipcop which is on sourceforge) and
have a problem.
The install is very slow and seems to be because of the hard drive not
running in DMA mode (I assume). It has run for many hours now and
is still untaring the install image. The trace below I think is because the
disk is running non DMA and is transfering individual bytes. If this
is the case, I will try to get the developers to change over the mode
of the drive, but want to ask any opinions here first.
255689879953d[HD ] IO write to 01f0 = 00
255689879954d[HD ] IO write to 01f0 = 00
255689879955d[HD ] IO write to 01f0 = 00
255689879956d[HD ] IO write to 01f0 = 00
255689879956d[HD ] concat_image_t.lseek(0)
255689879956d[HD ] concat_image_t.write 512 bytes
255689879956d[HD ] Raising interrupt 14 {DISK}
255698382177d[HD ] 8-bit read from 01f7 = 58 {DISK}
255698383044d[HD ] 8-bit read from 01f7 = 58 {DISK}
255698383247d[HD ] IO write to 01f0 = 5089
255698383248d[HD ] IO write to 01f0 = 474e
255698383249d[HD ] IO write to 01f0 = a0d
255698383250d[HD ] IO write to 01f0 = a1a
255698383251d[HD ] IO write to 01f0 = 00
There are 256 IO write lines then the same concat_image.
The configuration includes a Hard drive and CD image, and
was booted from a floppy install disk. Network is configured
and is inactive in the install.
any opinions?
