Hi Olaf (and the others), thanks for your kind and fast response.

The Maxtor 54098U8 will be the only EIDE device in the machine. So would it be satisfactory, to run it with the on board EIDE controller ??? But you also told me, that the CPU utilization is less with UDMA/66. So ... if I want to save some CPU cycles, should I nevertheless use UDMA/66 ?! > Those Promise and Abit etc. Controllers come with their on BIOS. > Therefore, if you buy one of these (about 100 DM here in Germany (~U$50)) > you are able to do UDMA/66. Soren, what controller do you have ? I think it would be a good strategy to buy a controller, that you have yourself, since I have the feeling, that EIDE sometimes has something of "black magic" ... Is this true ??? Or is it just my personal paranoia ? ;-)) Soren, could you please tell me, what ATA controller I should buy to have a smooth migration from SCSI to EIDE ? That would be very kind ! I'd like to make the deal tomorrow if the disk is available ;-)) Andreas /// -- Andreas Klemm http://www.FreeBSD.ORG/~andreas http://www.freebsd.org/~fsmp/SMP/SMP.html powered by Symmetric MultiProcessor FreeBSD Get new songs from our band: http://www.freebsd.org/~andreas/64bits/index.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
