J. Vermillion, Winter Park, FL Lines: 31 Speaking of the new C. Ltd Kronos controller ("Quotes, what quotes?"): I also received and installed my auto-boot chips for my A2000 C. Ltd. Kronos hard drive controller card. After it wouldn't auto-boot regardless of how many times I kicked the machine (just kidding...) I called their technical help number (non-toll-free) and spent about ten minutes with a helpful guy who told me to download a file off of the BBS and run a certain 'convert' program to fix certain problems with their "older" cards. After this (another non-toll-free call, approximately 15 minutes), everything worked fine. D*mn, should have thought of this fix myself... :) Regardless, my times (diskperf v3.0) are around 70K read with a 1024 buffer, and 54K write. Are you sure your read time (680K) is correct? Needless to say, compared to other system performances being posted, I am not impressed with the "Faster than DMA!" Kronos controller. Given, my drive is an Adaptec 4070 controlled model with an unknown access time (10 seconds :) ), bought from C. Ltd. ages (about a year and a half) ago, but those times are still disappointingly slow. Anyone else have a similar story or experience? Oh, these incredibly-fast times are realized with an interleave of four (for the Adaptec), turning on all the BlockReads/BlockWrites, and worst of all, disabling IRQ interrupts (i.e., can't modem and use the drive at the same time as it introduces garbage due to the interrupts not being serviced at the right time). A painful way to get the speed improvements I so desperately need... So, where's a FAST hard drive system for under $5? Oh, but be about 50 megs... -- ****************************************************************************** * (uiucuxc, hoptoad, petsd)!peora!tarpit!bilver!alj PLink: DUNG * * alj@bilver.UUCP GEnie: A.JOHNSONJR * ******************************************************************************
