HD Install :: can't boot frugal (0.9.2) off 1.4 CD...

I accomplished my first frugal install yesterday on an old HP pavilion, 166 Mhz, pentium, 32 MB ram, 540 MB HD(rescued from the trash dumpster!) using my old 0.9.2 CD & then downloaded the 1.4 iso last night with the intention of upgrading my frugal install. This box won't boot off the 1.4 CD but still boots off the 0.9.2 CD. The md5 sum checks out & my other machine( AMD Athlon, 512 ram, 80 GB HD) boots off the 1.4 CD, so it seems like I got a good burn. Is it normal for this to happen?(because of the different versions or something?) Do I need to delete my partitions & just do a fresh frugal install with 1.4?(if it will boot up then) If so it's not a problem this time since I just installed & have no data there to worry about backing up, but it seems like it should boot up anyway. Thanks for any info.

p.s. 1.4 looks slick on my other machine, I'm running 2 installs of Libranet 3.0 on there & have 4+ GB of free space where dsl 1.4 will soon reside!

Well I thought it would be simple, but...       I booted off the 0.9.2 CD & deleted my partitions with cfdisk, then tried to boot off the 1.4 CD, it still wouldn't boot off that (in fact it won't boot off any other CD, only the 0.9.2 CD) When I reboot with no CD loaded, It boots off the HD with the old frugal install. I've repeated this several times & can't seem to get 0.9.2 to go away. Actually when I delete everything it will not boot up off the HD, but as soon as I boot off the 0.9.2 CD the old frugal install is back. Maybe I'm missing something, but I'm sure I wrote the table to the disk & rebooted (several times) & it appears like everything should be gone, but...hope this makes a little sense...I was up late last night... ...thanks for any ideas ...wk
